Surge Anticipating Valve -- Diaphragm Pilot Cast Iron
Pilot-operated surge anticipating valves that protect pipelines from water hammer caused by pump start-up and shut-down. A high-sensitivity pilot senses the initial pressure drop when a pump stops and opens the main valve before the returning pressure wave arrives, dissipating surge energy harmlessly. When pressure stabilises, the valve closes slowly to prevent secondary surges. Self-acting design requires no external power. Cast iron body for water and wastewater pump stations.
