I. Introduction of H42 Vertical Check Valve
严格按API6D、GB/T12235 标准设计制造,本系列阀门正常处于关闭状态，由于管线中进口端介质的压力作用，而克服弹簧阻力使阀门开启。 H42 vertical check valve is strictly designed and manufactured in accordance with API6D and GB / T12235 standards. This series of valves is 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. 由于采用弹簧支撑阀芯，故采用立式安装或卧式装均可。 H42N vertical check valve uses spring to support the spool, so 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.
