Pressure Sustaining and Pressure Reducing Valve 1023

Hydraulically operated control valve with independent Pressure Sustaining and Pressure Reducing functions. It sustains minimum pre-set upstream pressure, regardless of fluctuating flow or varying downstream pressure, and it prevents downstream pressure from rising above maximum pre-set level, regardless of fluctuating flow or excessive upstream pressure. 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.

Typical Product Applications
  • Maintaining pre-set maximum pressure in pipe lines through the

day for leakage reduction

  • Pressure reduction for main off-branching lines requiring lower

pressure

  • Sustaining sufficient pressure at upstream in case of pressure

drop

  • Elimination of pressure fluctuation from dynamic pressure losses

at end consumers

  • Supplying safe pressure to facilities and households with low

pressure rated appliances

  • Prioritizing upstream consumes over downstream high demand
  • Preventing line emptying in gravity lines
