Direct-activated Pressure Relief、Sustaining、Back Valve

Direct-activated Pressure Relief、Sustaining、Back Valve

Features

    • When the inlet pressure directly responds to the pressure control chamber to adjust setting pressure, the response is sensitive and adjustment can be very precise.


    • The valve’s body and cover are connected with bolts and nuts instead of thread. This kind of design brings easy and tight seal.


    • The inlet pressure can be directly read form the gauge port PT 1/8″.

72 Direct-activated Pressure Relief、Sustaining、Back Valve

The valve is a diaphragm actuated pressure relief Valve. It opens automatically against the adjustable, preset spring loading whenever line pressure exceeds the setting of the spring. It is held in a normally closed position by the force of the compression spring. Effective diaphragm area is large in relation to the seat area and the action therefore is positive, precise, and dependable.
