Scope of application

H42H vertical lift check valve is strictly designed and manufactured in accordance with API6D and GB / T12235 standards. This series of valves are normally closed. Due to the pressure of the medium at the inlet end of the pipeline, the valve resistance is overcome and the valve opens. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the valve core toward the valve seat to close the valve, preventing the medium from flowing backward, so it acts as a check. Because the vertical check valve uses a spring-supported spool, it can be installed vertically or horizontally. It is widely used in pipelines in various working conditions such as petroleum, chemical, pharmaceutical, and power industries.
