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.

Second, forged steel globe valve structure type

1, full diameter or reduced diameter;
2, rod with a bracket;
3, self-aligning at both ends of the packing pressure sleeve;
4, with wound gasket seal type valve cover, threaded seal type valve cover, or Self-sealing bonnet
5, body inverted seal;
6, socket welding ANSI / ASME B16.11;
7, the threaded end (NPT end) according to ANSI / ASME B1.20.1.
