ZZYVP Pilot Operated Pressure Regulator, Connection flange ends / welded ends / threaded ends

The ZZYVP pilot operated pressure regulator valve is a type of self-actuated control valve. Pilot operated pressure control valve doesn't need exterior energy, and uses the power from the controlled medium since it's source of energy, and introduces the pilot from the pressure regulator valve to manage the positioning of the valve plug to alter the intercepting area, therefore altering the medium flow from the pilot operated pressure control valve and stabilizing the downstream pressure.

The pressure setting is recognized by modifying the spring around the pilot, so it's convenient, fast, labor-saving and time-saving.It may be set continuously within the running condition, and also the structure is straightforward and also the maintenance workload is small. The decompression ratio is ≤4000:1,and also the control precision is high the experience is sensitive and also the sealing is nice pilot operated pressure regulator valve is broadly utilized in the automated charge of gas pressure reducing and current regulation in a variety of industrial equipment, especially appropriate for that nitrogen sealing system from the storage tank.The stop valve can be used being an accessory. Before pilot operated pressure control valve working, close the stop valve to avoid overpressure and impurities from entering the actuator to safeguard the diaphragm and seals within the actuator and also to avoid overpressure and overall valve damage.

The Features of Pilot Operated Pressure Regulator Control Valve: 

1. The pressure setting is recognized around the pilot, therefore the pilot operated pressure regulator valve works, fast, labor-saving, time-saving and could be continuously occur the important condition

2. The control precision of pilot operated pressure control valve is all about 1 occasions greater compared to ZPL610 self-operated type, so it's appropriate for occasions where require high control precision

3. For the similar valve, the regulation range is wider compared to ZPL610 self-operated type

4. The response is especially sensitive, and incredibly small pressures (for example 50mm water column pressure) or minimal pressure changes could be perceived

5. The decompression ratio of pilot operated pressure regulator valve is especially large, for instance .8 MPa upstream, 50 mm H2O downstream, and also the pressure difference ratio reaches 1600.
