The pilot valve senses the downstream pressure through a connection at the valve outlet. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm. The downstream pressure is maintained relatively steady at the pilot set-point.

The solenoid shut-off / override interrupts the PR function to close off the main valve. The valve is available as either normally open where the solenoid is energized to close the main valve or as normally closed where the solenoid is de-energized to close the main valve.


    Excellent low flow stability
    Fast-acting solenoid override
    Operates as normally open or closed
    Easily and precisely set downstream pressure

pressure reducing valves with downstream surge control are based on the 106-PG or 206-PG main valve.

Pressure reducing pilot valve senses the downstream pressure through a connection at the valve outlet. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm. The downstream pressure is maintained relatively steady at the pilot set-point.

The surge pilot senses the downstream pressure. If the pressure rises above the pressure reducing pilot setting and reaches the surge pilot setting, the surge pilot opens in order to close the main valve rapidly.

There are various designs and types of pressure-regulating valves. The spring-loaded reducer and the pilot-controlled valve are the most common.
Spring-Loaded Pressure-Reducing Valves

The spring-loaded pressure-reducing valve is commonly used in pneumatic systems. It is often referred to as a pressure regulator. The valve simply uses spring pressure against a diaphragm to open the valve. On the bottom of the diaphragm, the outlet pressure of the valve forces the diaphragm upward to shut the valve. When the outlet pressure drops below the set point of the valve, the spring pressure overcomes the outlet pressure and forces the valve stem downward, opening the valve. As the outlet pressure increases, approaching the desired pressure, the pressure under the diaphragm begins to overcome spring pressure, forcing the valve stem upward and closing the valve. You can adjust the downstream pressure by turning the adjusting screw, which varies the spring pressure against the diaphragm. This particular spring-loaded valve will fail in the open position if a diaphragm rupture occurs.
Pilot-Controlled Pressure-Reducing Valves

Pressure Reducing Valves are designed to reduce incoming water or steam pressure to a safer constant predetermined downstream level. Depending on the type of valve, the downstream pressure is established by a pressure adjustment setting on the valve or by an external sensor. Pressure Reducing Valves are utilized in residential, commercial, institutional, and industrial applications.

Automatic control valves are used in commercial and industrial applications to control water flow or pressure. We offer automatic control valves that are used to ensure uninterrupted water service during emergencies, maintain a constant liquid level in tanks, automatically reduce a higher upstream water pressure to a constant downstream pressure, and for other purposes

The risks to drinking water quality from backflow contamination incidents pose a constant threat—whether they’re nuisance, non-health hazards, or serious public health events. Plumbing codes mandate that potable water supplies be protected against backflow at all cross-connections. We offer the largest selection of backflow prevention solutions for any application.

Pressure Reducing Valve
Automatic Control Valves, Pressure Reducing Valves

A Pressure Reducing Valve (PRV) is an Automatic Control Valve designed to reduce a higher unregulated inlet pressure to a constant, reduced downstream (outlet) pressure regardless of variations in demand and/or upstream (inlet) water pressure.
Pilot Operated Pressure Reducing Valves

The throttled position of the main valve is controlled by an adjustable pilot valve operating in conjunction with an orifice (or needle valve). The pilot valve senses the downstream (outlet) pressure and reacts immediately as the outlet pressure increases or decreases with varying demand.

The pilot senses the downstream (outlet) pressure and reacts immediately to add or remove water from the top of the main valve diaphragm assembly, allowing the valve to reposition and throttle as the outlet pressure tends to increase or decrease with varying flow demand. The pilot diaphragm will automatically sense the changes in the flow of the system as it continuously controls the main valve to throttle or to open or close and maintain the desired, preset reduced outlet pressure. The throttling action of the main valve provides the required reduced downstream pressure.

Pressure Flow Control (Modulation) Valve-

• Size Range : 1/2″ to 4″ Screwed / Flangedd
• Pressure Modulation Valve is a pressure reducing valve with a special (Patented) pilot that increases downstream pressure as flow increases.
• The PFC valve alters and controls pressure with flow to create virtually constant pressure at the critical pressure point in a system. It will also automatically adjust for distribution friction losses. The PFC valve will deliver consistent performance as it has no electrical components and is not affected should the valve chamber be flooded. The valve may be used wherever a standard PRV is installed.
• Reduces pressure when demand is lower resulting in reduced leakage losses and pipe breaks
• Compensates for pressure loss in a long pipeline to deliver virtually constant pressure at all times at a distant point
• Simple to set-up and adjust
• Pressure Management Valve
• Pressure Management Valve is a simple package to save water loss and money. It meets system needs by providing higher pressure when called for 24/7 and reduced pressure to save water leakage (and money) at all other times.
• An orifice with a low pressure drop 1.0 psi, (0.07 Bar) is installed upstream of a standard pressure reducing valve fitted with an extra pressure reducing pilot and a sensitive differential pilot which switches between 2 pressure reducing pilots to suit the system flow demand. High flow demand or fire flow will cause the differential pilot to automatically switch control from the low pressure to the higher pressure pilot. The action is then reversed when flow demand falls below the differential pilot set point valve position by modulating the pressure above the diaphragm. The downstream pressure is maintained relatively steady at the pilot set-point.
• Substantially reduces water loss (non-revenue water) due to leakage
• Decreases downstream pipe bursts and associated repair costs
• Allows constant reliable pressure to users, minimizing over pressure at off peak (flow) periods

Product Details:

• The 4Matic Make Pilot Operated Pressure Reducing Valve is designed for applications where the reduction of high inlet pressures to a safe and stable outlet pressure is required. The pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between the closed and open position ensuring a constant downstream set pressure. Once the downstream pressure reaches the pilot setting, the main valve will seal shut preventing damage downstream. Pressure regulation is not dependent upon flow rate, resulting in minimal pressure loss through the valve.
• Like direct acting pressure reducing valves, these valves are self-powered. Pilot operation provides accurate control under large load change conditions. Available in iron, cast steel and stainless steel in sizes 1/2" to 8".

Silent Features

• Valve Body is made by Stainless Steel #316, suitable for fluid, air and oil.
• Larger diaphragm is more sensitive to pressure.
• Pressure Adjusting Range  : 0.02 ~ 0.2 Kgf/cm
• Applied Temperature  : -15 ~ 80 °C
• Valve Body Testing Pressure   : 16 Kgf/cm2
• Maximum Applied Pressure   : 10 Kgf/cm2

• Media also available in Oil Gas and Air.
• Material also available in Aluminium and Bronz.
• The by-pass valve is set 5 psi / 0.35 bar higher than the main valve. Under low flow conditions, the main PR valve closes and the by-pass stays open, controlling the pressure at very low flows without seat chatter.
• The pilot valves sense the downstream pressure through a connection at the valve outlet. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm. The downstream pressure is maintained virtually steady at the pilot set-point.
• In contrast to pressure relief valves, which affect the level of input pressure (i.e. pump pressure) fed into the hydraulic system, pressure reducing valves are used to influence the output pressure of the hydraulic system to a subsystem (e.g. actuator pressure).
• Reducing the input pressure (primary pressure) or maintaining a particular output pressure (secondary pressure) is achieved at a set value which is below the varying pressure occurring in the main hydraulic circuit. It is thus possible to reduce the pressure in one part of the circuit to a lower level than the system pressure.
• The pressure control valve is normally open.
• A hydraulic system can only function  as per requirements - by using valves. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose. Get advice and suggestions from DTA in order to select the appropriate hydraulic valve, in terms of size and function, that suits your application and your budget.
• Pressure reducing valve is a type of pressure control valve. This type of valve is used to maintain constant reduced pressure in a pipeline where the flow is fluctuating. This type of valve (which is normally open) is used to maintain reduced pressures in specified locations of hydraulic systems. The high incoming pressure is reduced to a constant pressure level to protect the important instrument.
• The principal parts of the reducing valve are the main valve; an upward-seating valve that has a piston on top of its valve stem, an upward-seating auxiliary (or controlling) valve, a controlling diaphragm, and an adjusting spring and screw.
• A pressure-reducing valve uses a spring-loaded spool to control the downstream pressure. If the downstream pressure is below the valve setting, the fluid flows freely from the inlet to the outlet.
• Reducing valve operation is controlled by high pressure at the valve inlet and the adjusting screw on top of the valve assembly. The pressure entering the main valve assists the main valve spring in keeping the reducing valve closed by pushing upward on the main valve disk/0
• The controlling diaphragm transmits a downward force that tends to open the auxiliary valve. The downward force is exerted by the adjusting spring, which is controlled by the adjusting screw. Reduced pressure from the main valve outlet is bled back to a chamber beneath the diaphragm to counteract the downward force of the adjusting spring.

How Does 4Matic  Direct Acting Water Pressure Reducing Valve Work?

Installed in series directly after the water meter in homes, commercial buildings, and manufacturing plants, a water pressure reducing valve automatically reduces the pressure from the water supply main to a lower, more sensible pressure.

 

Water entering the valve from municipal mains is constricted within the valve body and directed through the inner chamber controlled by an adjustable spring loaded diaphragm and disc. Even if the supply water pressure fluctuates, the pressure reducing valve ensures a constant flow of water at a functional pressure, as long as the supply pressure does not drop below the valve's pre-set pressure.

internally pilot & piston operated pressure reducing valves are very compact in design & versatile type for accurate regulation with the widest possible range of flow
The full lift type main valve assembly & Globe type body design is capable of delivering very high flow rates with greater accuracy
The internally pilot controlled pressure reducing valves are best suitable for use in continuous distribution application
The constant outlet pressure (Down stream pressure) is accurately maintained right up to maximum rated discharge capacity of the valve and is unaffected by changes in inlet pressure or flow rate
A positive tight shut off ensured by accurate guiding of the pilot & the main valve assembly

    Pressure regulator is assembled with stainless steel trims to use for Steam, Air & Gas applications for low and medium pressure range
       Removable cap to allow easy adjustment
    Enclosed spring chamber eliminates diaphragm or spring fouling due to atmospheric condition
    Pilot valve and seat removable with PRV in line
    Carbon ring to minimize piston seizing
    Main valve and seat removable with PRV in line
    Inlet filter screen minimizes fouling of pilot valve due to dirt

• 4Matic Offer High Flow Multi Functional Type Pressure Reducing Valves Suitable for Air, Water, Steam, Gas & Oil ect.

  Features

• Smart Design with High Flow Characteristics
• Pressure reducing valve can be installed in water supply, air conditioning and fire control systems to maintain the Constant outlet pressure.
• The pressure reducing valve used a sub-valve (pilot valve) to control the main valve. When the outlet pressure reaches the setting range of pressure reducing pilot valve, the pilot valve will automatically sense the outlet pressure and adjusting the pressure of the back pressure chamber in the main valve, so the valve gate can be opened and consequently maintains the out let pressure.
• The pressure gauge on the pilot valve shows the outlet pressure. When the outlet opens, the valve of the pressure gauge will decrease.

Product Details:

There are two types of 4Matic pressure reducing valves, direct acting and pilot operated. Both use globe or angle style bodies. Valves used on smaller piping diameter units are cast from stainless steel; larger piping diameter units are made from ductile iron or Cast Iron or Cast Steel or Stainless Steel. Direct acting valves, the more popular type of a water pressure reducing valves, consist of Globe-Type bodies with a spring-loaded, heat-resistant diaphragm connected to the outlet of the valve that acts upon a spring. This spring holds a pre-set tension on the valve seat installed with a pressure equalizing mechanism for precise water pressure control.

Product Details:

• Back pressure regulators work differently than standard, or pressure reducing regulators, and it is important to define the difference.
• Pressure reducing regulators reduce a higher supply pressure at the inlet down to a regulated lower pressure at the outlet (downstream). Back-pressure regulators work the opposite way. They regulate the higher inlet (upstream) pressure by opening up only as much as necessary to hold back the desired pressure at the inlet (upstream).
• Back pressure regulators work just like relief valves, but the emphasis is on steady state pressure control instead of on/off pressure protection.

• 4Matic Multi function Type Control Valve with Manual Controller can be used as isolating valve and also for flow controlling application.

Two-Stage Serial Reduction Configuration

 

The two-stage serial reduction approach uses two 4Matic valves in series to reduce or eliminate extreme variations between the water main's inflow pressure and the desired, final reduced pressure. Two stage reduction is recommended when initial pressures are 200psi or greater, or when the desired pressure reduction ratio is greater than 4:1, e.g., from 200psi to 50psi, or where the inflow pressure fluctuates greatly. The advantage of two-stage serial reduction is that neither valve is subjected to extreme pressure differentials, thus prolonging valve life and delivering more precise pressure regulation.
