Surge Anticipating Control Valve IR-WW-735-M

The Model 735-M 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 735-M smoothly closes drip tight as quickly as
the relief feature allows, while preventing closing surge.
The valve also relieves excessive system pressure.
