Surge Anticipating Valve

Hydraulically operated, diaphragm actuated, off-line surge anticipating valve that immediately opens in response to the pressure drop associated with an abrupt pump stoppage. The pre-opened valve dissipates the returning high pressure wave, thereby eliminating the surge. The valve smoothly closes drip tight as quickly as the relief feature allows, thereby preventing closing surge. The valve also relieves excessive system pressure.

Bermad 700 Series valves are hydraulic, pilot operated, oblique pattern, globe valves with a seat assembly and double chamber unitized actuator that can be disassembled from the body as a separate integral unit. The valve’s hydrodynamic body is designed for an unobstructed flow path and provides excellent and highly effective modulation capacity for high differential pressure applications.

The 700 Series operates under difficult operating conditions with minimal cavitation and noise. They are made of the highest quality materials, suitable for different mining applications.
