First, forged steel globe valve overview

Forged steel globe valve has three kinds of bonnet design, the first is the bolt-type bonnet, connected by concave and convex surface, using stainless steel with flexible graphite spiral wound gasket, ring can also be used on request connection, and the second is welded bonnet , Through the threaded seal after welding, can also be used directly on demand rigid welding, the third is a self-sealing valve cover, threaded and self-sealing valve cover connection.
