Brief introduction:

 

Forged steel gate valves are available in three bonnet designs. The first design is the Bolted, with male-female

joint, spiral wound gasket, made in F304L/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.
