Lift Wafer Check Valve
Product Description The Lift Wafer Check Valves consists of valve body, disc and spring. It is installed horizontally or vertically in the pipeline system to prevent the media from backstreaming. The valve has the advantages of short structure, small volume, light weight, quick closing of disc,...
The Lift Wafer Check Valve can only be installed in a horizontal pipe. The disc can be used in a high pressure small caliber check valve with a ball. The valve body has the same shape as the globe valve, so its fluid resistance coefficient is large. The structure is similar to the globe valve, and the valve body and disc are the same as the globe valves.
1. When the medium is flowing in the prescribed direction, the disc is opened by the medium force; when the medium is countercurrent, the disc closes because of the weight of the disc and the reverse force of the medium, which makes the disc close to the sealing surface of the valve seat and prevents the medium from countercurrent.
2. the sealing surface of valve body and disc is made of stainless steel surfacing.
3. the structural length of the valve is regulated by GB12221-1989, and the size of the flange connection is JB/T79-1994.
