H42Y Flanged High Pressure 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 JB 450.
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.
