Bermad Model 420 - 55 - 2 way Pressure Reducing Solenoid Valve

The Bermad Model IR-420-55 Pressure Reducing Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. The Bermad Model IR-420 - 55 opens and shuts in response to and electric signal.


Features and Benefits

  • Line Pressure Driven PRV, Electrically Controlled On/Off
    - Projects downstream systems
    - Wide range of pressures and voltages
    - Normally Open, Normally Closed or Last Position
  • Advanced Glove Hydro-Efficient Design
    - Unobstructed flow path
    - Single moving part
    - High flow capacity
  • Fully Supported & Balanced Diaphragm
    - Requires low opening and actuation pressure
    - Excellent low flow regulation performance
    - Progressively restrains valve closing
    - Prevents diaphragm distortion
  • User Friendly Design
    - Easy pressure setting
    - Simple in-line inspection and service

Bermad model 420 - 55- 2 way pressure Reducing Valve -Operation

The Needle Valve [1] continuously allows line pressure into the Control Chamber [2]. The pressure Reducing Pilot [3] senses downstream Pressure [P2], and throttles when it rise above setting. Pressure then accumulates in the control chamber causing the Valve to throttle closed, decreasing [P2] topilot setting. The pilot releases accumulated pressure when [P2] falls below setting, thereby causing the Valve to modulate open. Closing the solenoid [4] causes pressure in the control chamber to accumulate shitting off the Valve.
