Shut-Off Pig Valves
The Shut-Off Pig Valve is a trunnion mounted ball valve. As indicated from the name the valve completely shuts off the flow of the piping and can be used as a single block and bleed or doubleblock and bleed valve.For certain applications a by-pass can be installed. The Shut-Off Pig Valve can be used as both a launcher o r a receiver using most types of pigs and will accept Bullet, Scraper and Spherical pigs, all in one configuration. Tulsa Valve performs 100% pressure testing on all of our Shut-Off Pig Valves. Please refer to the Tulsa Valve Shut-Off Pig Valve brochure for detailed information.
