Thanks for the help, the gasket manufacture has relaxed the requirement, but I find it difficult to understand why the valve vendor does not have a torque specification.
They are using only a torque wrench and per the gasket supplier they are trying to torque these valve flanges to 200 ft-lbs. They are cast iron raised face flanges that utilize 3/4" bolts. Biggest guy goes about 150lbs, but he loks a little like the Governor of California.
Curious what is ANSI Torque Specifications for 300 lb raised face flanges. I am currently following the torque specifications for the gasket but I am cracking cast iron raised face flanges on control valves.
