Multifunctional Water Pump Control Valve DN50-300mm 1.6/2.5MPa for Water Supply Systems
Ductile iron cast steel pump control valve combining electric valve, check valve, and water hammer eliminator functions. Features automatic operation, high flow rate, low pressure loss, and triple water hammer protection. Suitable for 0-80°C water systems with nominal diameters from 50-300mm and pressure ratings up to 2.5MPa.
Intelligent valve installed at pump outlets in water supply systems and high-rise buildings to prevent backflow and eliminate water hammer phenomena.
This advanced control valve integrates three essential functions: electric valve operation, check valve functionality, and water hammer elimination. Designed to automatically operate according to pump start/stop procedures, it ensures system safety while minimizing pressure loss and maximizing flow efficiency.
