减压阀 200X

产品详情

产品简介：

减压阀一般分为隔膜阀和活塞阀两大类，本公司生产的减压阀口径在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。减压阀主要控制主阀的固定出口压力，主阀出口压力不因进口压力变化而变化，并不因主阀出口流量的变化而改变其出口压力。广泛适用于工业给水、消防供水及生活用水管网系统。Products Introduction:Pressure reducing 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. Pressure reducing valves mainly control the fixed export pressure of the head valve; the export pressure of the head valve doesn’t be change with the import pressure’s change and the export flow’s change of the head valve. It is widely used in the network system of the water supply、fire water supply and life water supply. 主要零部件材质：Material of Main Parts
