1.I need reference websites for man 2

1.I need reference websites for manufacturers of 1/2" NPT threaded pressure relief valves to be used on pipeline ball valves that will relief the body pressure form ASME 150 to ASME 1500 lbs.

2. Also 1/2" NPT pressure relief valve sites to be used up to 10 barg instrument air. The valves will be used in the air supply to pneumatic actuators and need to conform to ASME standards as well.
Would appreciate some input

Do a google for Farris and Consolidated (Consolidated is now combined with Anderson-Greenwood, another reference I would have given). All can supply you with relief valves for what you need.

I'm not sure what you mean by "body pressure form ASME 150 to ASME 1500 lbs"

Stop at ISA :

http://www.isadirectory.org/online/prod2.cfm?ID=815250

and choose a Relief valve manufacturer.
My recommandations: See TD2K names and add : Crosby Valve Inc. (MA) and one of Tyco companies

19000 Series is 1/2" and larger will do the job.

Andersongreenwood has merged with Crosby
Crosby Omni is another good choice.

Low capacity, low price alternative
good valve for thermal relief applications
