The preferred body design is with socket-weld ends, but grayloc, butt-weld, flanged, and screwed ends are also available in ratings from 150 to 2500 psi / 10.3 to 172.4 bar, with special applications to 15,000 psi / 1034 bar. Offset globe construction is generally less expensive than in-line construction.
Most common maintenance problems with comparable globe valves are associated with cage guiding where close metal-to-metal contact between the cage and plug often results in galling and binding. Conversely, the Mark Two is double-stem guided, completely avoiding contact between the plug and seat retainer. Top entry trim with a clamped-in seat also permits easy, quick maintenance.
Features
- Same rugged design as the Mark One series
