The Model 735-55-M Surge Anticipating Valve with Solenoid Control is an off-line, hydraulically-operated, diaphragm-actuated valve. The valve immediately opens in direct response to any power failure, even prior to the pressure drop associated with abrupt pump stoppage. The pre-opened valve dissipates the returning high-pressure wave, eliminating the surge.

The Model 735-55-M—sensing line pressure—smoothly closes drip-tight as quickly as the relief feature allows, while preventing closing surge.
