Screw-Down Stop Check Valve

The screw-down stop check valve combines the functions of the globe valve and the check valve and is mainly used on marine vessels.
The valve body and the valve stem are not connected. Normally used as a lift check valve, this valve can be sealed when necessary by loading with the stem, as the globe valve.
