The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure and opens fully upon line pressure drop.
CCDV = Control Chamber Displacement Volume • BSP.T = Internal Threaded • BSP.F = External Threaded • Other End Connections are available on request. For dimensions and weights of adapters or valve with adapters please contact us.
