Features
1. Good effect to water hammer removal, Integrating the technical principles
of water hammer remmer removal by means of slow- open, quick-closeand slow-close SO as to prevent the water hammers at both pump startand stop from being formed.
2. Easy operation.The valve will automatically open or close per the oper ation
procedures of the pump once the On-Off button of the pump's motor isoperated.
3. Good effect of energy saving. The valve body is so designed as full-path
straight-flow type,resuling in a small pressure loss, a big flow,a smallvotume and a light weight.
