• 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. Special Design Namur style Level Operated Ball Valve mounted on main valve for operation. Its simple Technical and heavy duty design impact a unique stands against other Control Valve. High Flow factor and simple Pilot Control makes its very user friendly.
• Exclusive design having for bigger sizes Municipal Water Supply Boards & cross country Pipe line Projects.
• High Cv Value, with Low Pressure Hammering via smooth operation in Actuator
• Lever Operated Low Torque PTFE Seated Ball Valve for smooth and trouble free operation
• Low Noise & Friction at the time of Controlling.
•  Vertical & Horizontal installation can be done.

The 4Matic Direct Acting Water Pressure Reducing Valve, commonly used in homes, commercial buildings, and manufacturing plants, operates by automatically reducing water pressure from the supply main. It maintains a constant and functional pressure even when supply pressure fluctuates.
Water enters the valve and is constricted within the valve body. An adjustable spring-loaded diaphragm and disc control the flow through the inner chamber. This ensures a steady water flow at a functional pressure, as long as supply pressure is above the valve's preset pressure.
The valve features an internally pilot and piston operated system, offering accurate regulation across various flow rates. Its design, with a full lift type main valve assembly and Globe-type body, enables high flow rates with accuracy. It's ideal for continuous distribution applications, maintaining constant outlet pressure despite changes in inlet pressure or flow rate. The pilot and main valve assembly work together to provide a secure shut off.
Stainless steel trims make the valve suitable for Steam, Air & Gas applications at low and medium pressure. A removable cap allows for easy adjustment, and the enclosed spring chamber prevents fouling due to atmospheric conditions. The valve can be serviced without removing it from the line. An inlet filter screen prevents pilot valve fouling due to dirt, while a carbon ring minimizes piston seizing.
Safety is crucial. Proper safety gear (safety glasses, safety shoes, hard hat) must be worn. Hammering while pressure is present is prohibited, as is using improper tools. Protection against burn injuries from hot surfaces is essential.
On-site, valves are labeled with maximum pressure ratings that must not be exceeded. Discharge connections should be cleaned and oiled before attaching downstream piping. Welding or heating the valve is not allowed. Regular inspections are vital, and repairs must be done by trained technicians under supervision or returned to the manufacturer.
In summary, the 4Matic Valve effectively reduces water pressure while ensuring safety and constant flow. Its design, internal mechanisms, and safety guidelines contribute to its reliable performance.
