水力电动控制阀一般分为隔膜阀和活塞阀两大类，本公司生产的水力电动控制阀口径在DN400mm以下者采用隔膜型，口径在DN450mm以上者采用活塞型，两者之动作原理类似。水力电动控制阀用于安装在给水管线上作为电动遥控开启和关闭的功能。同时可加装速度调控装置，可取代启闭闸阀或蝶阀的大型电动装置。维修简单，使用方便，安全可靠。

Hydraulic Electric Control valves are usually divided into diaphragm valves and piston valves two categories, the caliber of the company’s production bellows DN500 using diaphragm type, and DN600 more in the use of piston type, whichever is the principle of similar moves. Hydraulic electric control valves are installed in the water supply pipeline as an electric remote control to open and close. Meanwhile the devices of speed control can instead the large electric devices of lift gate valves and butterfly valves. Maintenance is simple, easy to use, safe and reliable.
