Shut-Off Pig Valves

TVC Model SHPV is a Shut-Off Pig Valve designed and released in 2011 with the state-of the-art ease-of-use and performance under the severest conditions. The trunnion blockmounted ball valve reduces both torque and stem loading, while adding longer life. The TVC Model SHPV is bi-directional for use as both launcher and receiver, and can be installed with a by-pass where needed.
