Features
The valve adopts the OPEN design, hence water supply will not be affected due to instability in inlet pressure.
When the outlet 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 outlet pressure can be directly read form the gauge port PT 1/8″.
Can be used individually, or can be used as a pressure reducing pilot.
