All gate valves processed with forging materials are collectively referred to as Forged Steel Gate Valves. The forging materials include ASTM A105, ASTM A350 LF2, ASTM A182 F5, ASTM A182 F304, ASTM A182 F304L, ASTM A182 F316, ASTM A182 F316L, etc.
When forged steel gate valves are mentioned domestically, they refer in particular to small-bore ones, with a nominal diameter range of DN10 to DN50, common pressure rating: German standard PN16 - PN320, American standard: Class 150 - 2500 LB, which can be produced and processed by adopting American standard or German standard sizes. The forged steel gate valve beyond DN50 needs to be customized.
Forged steel gate valves are suitable for small diameter pipelines of Class 150 to 2500 LB, working temperature -29 to 425 °C (carbon steel) or -29 to 500 °C (stainless steel) to cut off or connect the medium in the pipeline. Forged steel gate valves are commonly used in oil pipelines.
A Bolted Bonnet Forged Gate Valve is a kind of forged steel gate valve whose bonnet and body are connected by bolt. Bolted Bonnet Forged Gate Valves are sealed with wound gaskets and are easy to maintain.
A Pressure Sealed Bonnet Forged Gate Valve is a kind of forged steel gate valve of which the body and bonnet are connected by thread and is self-sealed by inner pressure sealing ring. One of the advantages of pressure sealed bonnet forged gate valves is that the higher the inter pressure is, the better the sealing performance is.
A Welded Bonnet Forged Gate Valve is a forged steel gate valve with the body and bonnet all welded and sealed. The main advantage of welded bonnet forged gate valves is that there is no external leakage.
