Pressure Reducing and Sustaining Valve IR-423-50-R

The BERMAD Pressure Reducing and Sustaining Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve that performs three independent functions. The BERMAD Model IR-423-50-R sustains the preset minimum upstream pressure, reduces downstream pressure to a constant preset maximum, and it either opens or shuts in response to a remote pressure command.

Product Features & Benefits
  • Hydraulic Pressure Control

-Line pressure driven
