4Matic make pilot operated pressure reducing valves provide stable pressure control with low pressure rise in applications where a specific pressure is needed for precise operation on functions that require regulated pressures up to 1 bar to 40 bar. Pilot operated reducing valves are designed with several pressure and flow ranges in order to give a higher degree of control with a variety of adjustment style options available. The additional valve stability due to the pilot operation make these valves ideal for functions such as brake releases, dual pressure circuits, pilot pressure control, and downstream pressure control on various types of machinery within the mobile and industrial markets.

Applications:
• Brake release

• Pilot pressure control

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.

    Excellent low flow stability
    Automatically reduces downstream surges during sudden demand reductions
    Easily and precisely set downstream pressure

• 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

The Direct Acting Pressure Reducing Valve (PRV) is designed to automatically reduce high upstream pressure to a controlled downstream pressure. It works without the need for an external actuator or pilot, ensuring a compact, reliable, and cost-effective solution.

Trusted worldwide, 4Matic Valves ensures every valve undergoes strict quality checks to meet international standards. Easy installation, minimal maintenance, and consistent performance make the Pressure Relief Valve the preferred choice for industries seeking efficiency and safety in one solution.

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.
