产品简介:
流量控制阀一般分为隔膜阀和活塞阀两大类,本公司生产的流量控制阀口径在DN500mm以下者采用隔膜型,口径在DN600mm以上者采用活塞型,两者之动作原理类似。流量控制阀设置在给水管线中。广泛适用于工业给水、高层建筑由水泵直接给水系统中,调节流量。
Products Introduction:
Flow 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. Flow control valves are installed in the water supply pipeline. It is widely used in the system whose water is supplied by the water pump, such as the industrial water supply and tall building, regulate flow.
