Product Description
The BERMAD 120-55-3 Way Pressure Reducing Control 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; and opens fully upon line pressure drop. This model either opens or shuts in response to an electric signal.
Features and Benefits
- Hydraulic Pressure Control with Solenoid Control
- Line pressure driven
- Protects downstream systems
- Opens fully upon line pressure drop
- Electrically controlled On/Off
- Engineered Plastic Valve with Industrial Grade Design
- Highly durable, chemical and cavitation resistant
- No internal bolts and nuts
- hYflow ‘Y’ Valve Body with “Look Through” Design
- Ultra-high flow capacity – Low-pressure loss
- Unitized Flexible Super Travel (FST) Diaphragm and Guided Plug
- Accurate and stable regulation with the smooth closing
- Requires low opening and actuation pressure
- Prevents diaphragm erosion and distortion
- Simple In-Line Inspection and Service

Technical Data
Operation
The Shuttle Valve [1] hydraulically connects the Solenoid [2] or the Pressure Reducing Pilot (PRP) [3] to the Valve Control Chamber [4]. When the solenoid is closed, the PRP commands the Valve to throttle closed should Downstream Pressure [P2] rise above the setting and to open fully when [P2] is below the setting. In response to an electric signal, the solenoid switches, directing line pressure through the shuttle valve into the control chamber, shutting the Valve. The solenoid also features local manual closing.
