Product Description
The BERMAD Model 130-55-X 3 Way Pressure sustaining valve is a hydraulically operated, diaphragm-actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting. It either opens or shuts in response to an electric signal.
Features and Benefits
- Line Pressure Driven, Electrically Controlled On/Off
- Prioritizes pressure zones & controls system fill-up
- Sustains upstream line pressure
- Opens fully upon line pressure rise
- 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 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 Sustaining Pilot (PSP) [3] to the Valve Control Chamber [4]. When the solenoid is closed, the PSP commands the Valve to throttle closed should Upstream Pressure [P1] drops below the setting and open fully when [P1] rises above the setting. In response to an electric signal, the solenoid switches, directing line pressure through the shuttle valve into the control chamber, thereby causing the main Valve to shut. The solenoid also features local manual closing.
