Product Type: Check ValveProduct Name: Silent Check ValveProduct Details:Place of Origin: ChinaCertification: ISO9001-CEProduct Descriptionsilent check valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.Silent Check Valves are named for their spherical body shape with the two halves of thebody being separated by an internal baffle. This has an opening that forms a seat onto which amovable plug can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem ratherthan threaded and are opened and closed by an actuator assembly. When a globe valve is manuallyoperated, the stem is turned by a handwheel.
