Surge Anticipating Control Valve BC-735-P
The Model BC-735-P Surge Anticipating Valve is an off-line, hydraulically operated, diaphragm actuated valve. The valve, sensing line pressure, opens in response to the pressure drop associated with abrupt pump stoppage. The pre-opened valve dissipates the returning high pressure wave, eliminating the surge. The Model BC-735-P smoothly closes drip tight as quickly as the relief feature allows, while preventing closing surge. The valve also relieves excessive system pressure. BERMAD 700 series valves are hydraulic, oblique pattern, globe valves with double chamber unitized actuator, that can be disassembled from the body as a separate integral unit. The valves hydrodynamic body is designed for unobstructed flow path and provides excellent and highly effective modulation capacity for high differential pressure applications.

A soft start/stop pump station with emergency surge protection – in a case of power failure sudden pressure drop due to column separation will activate the BC-735-P to open and anticipate any returning surge from the riser, thus reducing water hammer damage and prolonging equipment lifetime.
