GTL-H42H Vertical Stainless Steel Check Valve

Vertical Stainless Steel Check Valve is normally closed, due to the pressure of the inlet medium in the pipeline, and overcome the spring resistance to open the valve. When the medium pressure at the inlet end is lower than the outlet end, the spring will push the valve core to the seat and make the valve close, prevent the medium upstream, so the start and stop effect. Due to the use of spring support valve core, so the use of vertical installation.
