Highlight: Forged Steel Swing Check Valve

Product introduction:

Forged steel check valves have three types of bonnet designs. The first is the bolted bonnet: for valves designed in this form, the body and bonnet are connected by bolts and nuts, sealed with a spiral-wound gasket (made of 316 stainless steel with flexible graphite insert). Metal ring joints can be used upon special customer requests. The second design is the welded bonnet: valves of this design feature a threaded connection between the body and bonnet, with full-weld sealing. Through-weld connections can be adopted for special customer requirements. The third is the pressure-self-sealing bonnet: valves with this design have a threaded body-bonnet connection, sealed by an internal pressure self-tightening ring.Check valves exist in three different structural designs: lift check valves, ball check valves, and swing check valves.
