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.
