Welding Welding check valve structure welded check valve specifications

Features 1. Product design and manufacture according to E101 and JB / T3595-93 standards, reasonable structure, excellent performance, modeling. 2. The valve in the cavity by pressure from the tight seal structure, the higher the media pressure, better sealing performance. 3. The manifold is welded at both ends of the connection, to adapt to different requirements of takeover. The valve seat sealing surface using Stellite (stellite) cobalt-based alloy cladding made of wear-resistant, high temperature, good anti-abrasion performance, long service life. 5. High temperature and pressure components of high quality heat-resistant alloy steel, safe and reliable, stable performance and long service life.
