SURGE ANTICIPATING VALVEModel 735-M-M5/M5L/M6
Hydraulically operated, diaphragm actuated, off-line surge anticipating valve that immediately 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 valve smoothly closes drip tight as quickly as the relief feature allows, thereby preventing closing surge. The valve also relieves excessive system pressure.
The BERMAD 700 Series large size control valves are hydraulically operated, diaphragm actuated type. Unique hydro-dynamic globe valve design with a special open plug provides high flow capabilities. The valves are available in the standard configuration or with an Independent Check Feature code “2S”.

Required data for surge analysis:Pipe profile and characteristic, pumping station full details, valves and reservoirs.
Notes• Full system data is required for surge analysis and optimal valve sizing.• A flow stem enables limiting valve opening stroke, adjusting precisely the required flow through the valve.• Recommended maximum flow velocity: 15 m /sec; 50 ft /sec.• Minimum operating pressure: 0.7 bar /10 psi. For lower pressure requirements consult factory.
