Pressure Relief/Sustaining Valve 1030
Pressure relief/sustaining hydraulically operated control valve that can fulfill either of two separate functions: When installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. When installed as a “branched from the line” circulation valve it relieves excessive line pressure when above maximum pre-set. The BERMAD 1000 is at the leading edge of control valve design, providing a valve that is free of the typical limitations associated with standard control valves. A unitized flexible diaphragm & guided plug provide a significantly ‘look through’ passage resulting in accurate & stable regulation and high flow capacity. The 1000 unique composite structure allows fast & simple maintenance by easy replacing of lightweight diaphragm assembly. It has a wide range of end connection types and sizes, including articulated flange connections isolating the valve from pipeline bending & pressure stresses.

- Unitized actuator unit – open, replace, close
- In-line serviceable – no need to remove from line
- All the benefits of a diaphragm actuated control valve
- Wide flow range
- Low flow stability
- Drip tight sealing
- Obstacle free flow pass
- Easy addition of hydraulic features
- Sustaining sufficient pressure at upstream in case of pressure drop
- High pressure safety relief valve in potable water pressure reduction systems
- As a safety device for pumping stations temporarily operated out of their regular regime, where stable and constant pressure relief is required
- Sustains pump discharge pressure, preventing pump overload and cavitation damage caused by excessive demand
- Preventing line emptying in gravity lines
- Pressure sustaining control of buildings reservoir filling systems such as: basement, roof-top, pressure breaking and emergency tanks, where the supply line also feeds additional high priority users
- As a safety device for pumping stations temporarily operated out of their regular regime, where stable and constant pressure relief is required
