Threaded Ball Check Valve

Size Range:DN25-DN80

Pressure: PN16

Body Material:DI

Disc Material:Steel+EPDM

Flanged Material:DI

Features: Threaded ball check valve is also called slide ball type check valve, using rubber coated rolling ball as the valve core, under the action of the medium, it can be rolled up and down on the integral slide of the valve body, so as to open or close the valve, good sealing performance, no water hammer. The valve body adopts full flow channel, large flow rate, small resistance, can be used in cold water, hot water, industrial and domestic sewage pipe network, medium temperature 0-80℃. It can be installed at the water outlet of the pump to prevent back flow and water hammer damage to the pump.
