Hydraulically Operated Nylon Reinforced Diaphragm Pressure Sustaining Valve
Description:
A500 can protect system from overpressure by exhausting excess pressure. The valve may only have to operate intermittently to prevent pressure surges that might occur on pump start, pump stop, or sudden downstream valve closure.
When A500 Installed in the main flow line,it works as a backpressure or pressure sustaining valve. In this configuration, the valve maintains a constant upstream pressure regardless of fluctuating downstream demand.
Feature:
Operates automatically off line pressure
Nylon-reinforced diaphragm.
Easily maintained without removal from the line.
Replaceable seat ring.
