Product parameters
The valve disc of the lifting check valve slides along the vertical center line of the valve body. The lifting check valve can only be installed on the horizontal pipeline. The valve body shape of the lifting check valve is the same as that of the globe valve (common with the globe valve), the upper part of the valve disc and the lower part of the valve cover are processed with a guide sleeve. The valve disc is opened by the medium thrust. When the medium stops flowing, the valve disc falls on the valve seat by its own weight and the medium thrust, and plays the role of blocking the medium countercurrent.
