Product Description

The DS101/201X piston type multi-function water pump control valve is an intelligent valve installed at the pump outlet of the large-diameter water supply network system to prevent medium backflow, water hammer and water hammer. The valve has three functions of electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system. The double-chamber and double-disc structure can quickly close 90% of the valve after the pump is stopped (to prevent the backflow medium from causing the pump to reverse), and then slowly close the remaining 10% (to eliminate destructive water hammer).
