This free 12-page brochure describes, illustrates, and specifies DAN-EX dual expanding plug valves.
With labeled schematics and full dimensional data, the literature covers a variety of 2 through 20 in. sizes and various ANSI ratings for both handwheel operated-reduced port and gear operated-reduced port designs.
A two-page labeled cutaway illustration points out 15 DAN-EX features. These include differential thermal relief (DTR) that automatically relieves pressure from the body cavity caused by solar or ambient temperature changes. Large-diameter plug trunnions are integral to the plug for strength and extend fully into the bonnet and lower plate for increased support and rigidity.
Full, illustrated explanation of how the valves work is provided along with body bleed and thermal relief valve options. The latter include DTR along with automatic body bleed valve, line relieving differential thermal relief, plus differential thermal relief (DTR) with gauge.
