Surge Control Valves Available At Pelmar Engineering Ltd.

The Model 735-M Surge-Anticipating Control Valves are off-line, hydraulically-operated, diaphragm-actuated surge control valves. The surge control valves, sensing line pressure, opens in response to the pressure drop associated with abrupt pump stoppage. The pre-opened surge control valves dissipates the returning high pressure wave, eliminating the surge.

The Model 735-M surge control valves smoothly closes drip-tight as quickly as the relief feature allows, while preventing closing surge.

The surge control valves also relieves excessive system pressure.

• Eliminates surge for all pumping systems:
• Booster & deep well, single & variable speed
• Eliminates surge for all distribution networks:
• Municipal, hi-rise buildings, sewage, HVAC, irrigation
• Difficult to maintain, remote locations, older systems

The Bermad Model 720 Surge Control Valves are hydraulically-operated, diaphragm-actuated, surge control valves that reduce higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.

• Flow and leakage reduction
• Cavitation damage protection
• Throttling noise reduction
• Burst protection
• System maintenance savings
