H42 (Y / W) vertical check valve

Product Overview

Vertical check valve: the valve is opened or closed by overcoming the spring resistance due to the pressure of the medium at the inlet end of the pipeline. When the pressure of the medium at the inlet end is lower than that at the outlet end, the spring pushes the valve core toward the valve seat to close the valve and prevent the medium from flowing backward, so it plays a check role. Vertical check valves are widely used in chemical, liquefied petroleum gas, fluid and other industries. According to the structure, check valves can be divided into lift check valves, swing check valves and butterfly check valves.
