Vertical Lift Check Valve
Main features and working principle:
1.Installed vertically or horizontally.
2.The valve keeps in closing normally. Because of the effect of the media pressure in the inlet,the valve
will open byovercoming the resistance from spring.
3.When the outlet pressure exceeds the inlet pressure,the valve will be closed under the spring's driving.
4.Can prevent the medium in the pipeline driving back.
