Notes: 1. Valve sizes 2”, 3” and 4” are multi/dual pressure class rated.
2. Minimum bore diameter of companion flanges.
3. Design wall thickness only. Contact factory for actual measurements.
General: 1. For pressure loss information please see page 14.
2. For ordering information please see page 18.
3. Dimensions are subject to change. Contact factory for certified prints when required.
Stud Selection
Notes: 1. Upon prolonged exposure to temperatures above 800°F, the carbide phase of carbon steel may be converted to graphite.
