Pneumatic diaphragm operated pressure reducing valve symbol is to use compressed air as the power source and cylinder as the actuator, and to drive the valve with the help of electrical valve positioner, converter, solenoid valve, retention valve and other accessories to achieve switching or proportional adjustment. The control signal of the automatic control system is used to complete the adjustment of the pipeline medium: flow, pressure, temperature and other process parameters. The characteristics of the pneumatic control valve are simple control, fast response, and intrinsic safety, and no additional explosion-proof measures are required.
1. Benefit of pheumatic diaphragm pressure reducing valve:
- easy control and operation
- Fast action
- much Safety
