I. Introduction of H42N Vertical Check Valve

H42N vertical check valve structure

阀瓣采用单阀瓣设计,沿着中心定位作升降运动,由于阀瓣的关闭行程短,并有弹簧加载,关闭速度快。 H42N vertical check valve disc adopts single disc design, which is positioned along the center for lifting movement. Due to the short closing stroke of the disc and spring loading, the closing speed is fast. The sealing surface is made of elastic nylon material, which improves the sealing performance and avoids the electrostatic spark caused by the impact of the medium pressure. It is applicable to the opening and closing device for connecting and cutting off the pipeline medium of the gas pipeline.


1. The valve is a fully-enclosed structure, which has no moving seal and never leaks.

H41N升降式止回阀 阻力小,利用流体压差和自身的重量实现升降。 2. The H41N lifting check valve has low resistance and uses the fluid pressure difference and its own weight to achieve lifting.

3. The sealing surface is made of polytetrafluoroethylene or nylon plastic, which improves the sealing performance.
