PRODUCT INFORMATION
835-M – High Pressure Surge Anticipating Control Valve
The Model 835-M High Pressure, Surge Anticipating Valve is an off-line, hydraulically operated, piston 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 835-M smoothly closes drip tight as quickly as the relief feature allows, while preventing closing surge. The valve also relieves excessive system pressure.
- Eliminates surge in all pumping systems:
- Booster & deep well, single & variable speed
- Eliminates surge in all distribution networks:
- Municipal, high-rise buildings, sewage, HVAC, irrigation
- Difficult to main, remote locations, & older systems
