A Pilot Operated Pressure Reducing Valve Manufacturer in USA is a valve that uses a pilot valve to control the flow of fluid through a main valve. The pilot valve senses the outlet pressure and adds or removes water from the main valve diaphragm assembly to reposition and throttle the valve. This allows the valve to respond to changes in flow demand and maintain close pressure control.
Functions:
1. Pilot Operated Pressure Reducing Valve Manufacturer in USA adjusts the main valve to open, close, or throttle to maintain the desired pressure.
2. Balances the downstream pressure against a pressure adjustment control spring.
3. If there’s no flow required in the low-pressure circuit
4. If high-pressure fluid leaks into the reduced-pressure section, the pilot operated relief valve returns it to the reservoir.
Advantages
1. It has a Compact size
2. Pilot Operated Pressure Reducing Valve Manufacturer in USA, these valves are good for applications that require significant pressure drop and modulation.
3. They have a tight downstream pressure control.
4. The valves offer a variety of control options
5. Valves seal more tightly as the system pressure approaches the set pressure
6. Higher operating-to-set pressure ratio
7. Valves have a greater seating force than spring-loaded valves, making them ideal for higher operating pressure gaps
8. Have a much greater capacity than standard bore valves of comparable size
