Muffler QT450 Flange Type Non Return Valve Silencing Sewage PN10 PN16 Iron

Muffler check valve QT450 sewage water gas oil PN16 PN10 iron

Function: prevent backflow of fluid

Features: the silencing check valve is mainly used in water supply,drainage, fire fighting, heating and ventilation systems. It can be installed at the outlet of the water pump to prevent medium backflow and water Silencing check valve is a new type of valve introduced in recent years. The valve disc rotates along the center line of the valve body to complete the closing work. This valve has novel structure, small volume, light weight and is suitable for installation and maintenance. It is generally installed on the drainage pipe. When working, under the pressure generated by the flow of media in one direction, the valve disc is opened; otherwise, the media is reversed When flowing back, the pressure coincides with the valve disc to produce a certain effect on the valve seat, cutting off the flow of medium and preventing the reverse flow of medium. Small fluid resistance, reliable sealing, stable opening and closing, wear resistance,long service life, oil pressure and slow closing are not affected by the medium, and have better energy saving effect.
