Lift type check valve. The material is usually: cast steel WCB, alloy steel WC6,WC9,CN7M(20# alloy steel). Stainless steel has CF8(M),CF3(M). Forged steel has A105,F304(L),F316L and so on. It is a valve that controls the one-way flow of the medium in the pipeline, and is used to prevent the backflow of the medium in the pipeline. Lifting check valve is suitable for medium and small diameter pipeline under various pressure, temperature and media control through or cut off the pipeline medium opening and closing device; Rely on the weight of the valve disc and fluid pressure difference to automatically prevent fluid backflow. The applicable medium is: water, oil, steam, etc.
