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.
