產品簡介：
本公司生產的多功能水泵控制閥一般安裝在水泵出口管道上。水泵啟動時閥門自動實現緩慢開啟，水泵停機時，閥門自動實現速閉或緩閉，有效減少水錘沖擊，特別適用于自動化供水系統(tǒng)，封閉效果好，關閉無噪音，操作維修方便，并具有節(jié)能的效果。
Products Introduction:
Multifunctional water pump control valves of our company are general installed in the pump export pipeline. When the water pump is starting, the valve will open slowly, and when the water pump is standing, the valve will close slowly or quickly. Effectively reduce the impact of the water hammer, particularly applicable to the automated supply system, close effect well, close no noise, operation and maintenance easy, and with the effect of energy-saving.
