產(chǎn)品簡介：
水力電動控制閥一般分為隔膜閥和活塞閥兩大類，本公司生產(chǎn)的水力電動控制閥口徑在DN400mm以下者采用隔膜型，口徑在DN450mm以上者采用活塞型，兩者之動作原理類似。水力電動控制閥用于安裝在給水管線上作為電動遙控開啟和關閉的功能。同時可加裝速度調控裝置，可取代啟閉閘閥或蝶閥的大型電動裝置。維修簡單，使用方便，安全可靠。
Products Introduction:
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.
