Swing Check Valve

Short Description:

Product Name: DIN Swing Check Valve
Valve Category: Non-return Valve (NRV)
Brand: Yiluoke
Technical Data: DN15-DN1000
Made In: China
Supplier: Xiamen Yiluoke Import and Export Trading Co., Ltd

Product Detail

A Swing Check Valve is equipped with a disc that rotates around a hinge or shaft. The disc rotates away from the valve seat to allow forward fluid flow; when the fluid stops flowing, the disc rotates back to the valve seat position to prevent backflow. The weight of the disc and fluid backflow affect the shut-off characteristics of the Swing Check Valve.
