The H42 Vertical Check Valve is designed and manufactured strictly in accordance with API6D and GB/T12235 standards. In normal conditions, this valve remains in a closed state. The valve opens when the pressure of the medium at the inlet end of the pipeline overcomes the spring resistance. When the pressure at the inlet end is lower than the pressure at the outlet end, the spring pushes the valve disc towards the valve seat, closing the valve and preventing the backflow of the medium, thus performing the check valve function. The H42N Vertical Check Valve, with a spring-supported valve disc design, can be installed either vertically or horizontally. This valve is widely used in pipelines across various industries, including petroleum, chemical, pharmaceutical, and power sectors, under different working conditions.
