Brief introduction£º
Forged steel check valves are available in three bonnet designs. The first design is the Bolted Bonnet, with male-female joint, spiral wound gasket, made in F304/graphite.Ring joint gasket are also available on request. The second design is the welded bonnet, with a threaded and seal welded joint. On request a full penetration strength welded joint is available .The third design is the pressure seal bonnet, with a threaded and pressure seal bonnet joint. The check valve is also available in three different design configurations. These are piston check, ball check, or swing check designs.
