Structural features

Flange high pressure lift check valve has the following three structural characteristics: 1, upper and lower body adopt flange connection; 2, manufacture and acceptance conditions are according to the provisions of JB450. 3, the disc and seat sealing surface use stellite cobalt-based hard alloy welding, with wear-resistance, high temperature resistance, corrosive resistance, good anti-abrasion performance, long service life. 4, the high temperature pressure resistant components are made of high-quality heat-resistant alloy steel, with reliable safety, stable performance, long service life. The valve has been widely used in high-pressure pipelines of a variety of chemical industry, metallurgy, iron and steel industry.
