Forged steel gate valve

Product overview:

Forged steel gate valves come in three bonnet designs. The first is a bolted bonnet, where the valve body and bonnet are bolted together, sealed with a spiral wound gasket (made of 304 stainless steel with flexible graphite) or a metal ring connection. The second is a welded bonnet, where the valve body and bonnet are threaded together, with a full weld seal. Full penetration welding is also available upon request. The third is a pressure self-tightening bonnet, where the valve body and bonnet are threaded together, sealed with an internal pressure self-sealing ring.
