product description

       Piston-type multi-function pump control valve is installed on the large-diameter water supply pipe network at the pump outlet, to prevent media backflow, water hammer and water hammer phenomenon intelligent valve. The valve combines electric valve, check valve and water hammer eliminator three functions, which can effectively improve the water supply system safety and reliability. Double-chamber, double-disc construction allows the valve to quickly shut off 90% after the pump has been stopped (prevents reverse flow from causing the pump to reverse) and then slowly shut off the remaining 10% (destructive water hammer) Piston Valves Reliable, high strength , Smooth action, to prevent the pump water hammer and water pump stop the occasion. Just operate the pump motor hoist button, the valve can be automatically opened and closed in accordance with the pump operating procedures, flow, pressure loss.
