Bermad 835-M Large Metal Hydraulic 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 and variable speed
• Eliminates surge in all distribution networks:
  • Muncipal, high-rise buildings, sewage, HVAC, irrigation
  • Difficult to maintain, remote locations and older systems
