Factory Direct Sales Cast Steel Swing Check Valve Pipeline Cast Steel Flange Swing Check Valve

• The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance. • The sealing surface is welded with C0-based hard alloy, which is wear-resistant, corrosion-resistant, abrasion-resistant, has good performance and long service life. • The built-in pin structure reduces external leakage points and is reliable to use. • When the pressure is ≥16.0MPa, the valve cavity adopts a self-tightening sealing structure. The higher the medium pressure, the better the sealing performance. • The material of the parts and the size of the flange and butt welding end can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
