产品详情产品简介： 本公司生产的多功能水泵控制阀一般安装在水泵出口管道上。水泵启动时阀门自动实现缓慢开启，水泵停机时，阀门自动实现速闭或缓闭，有效减少水锤冲击，特别适用于自动化供水系统，封闭效果好，关闭无噪音，操作维修方便，并具有节能的效果。Products Introduction:Multifunctio
nal water pump co
ntrol 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. 主要零部件材质：Material of Main Parts:
