Shut-Off Pig Valve
Triple S Solutions supplies the Tulsa Pig Valves Shut-Off Pig Valve designed for cost-effective pipeline maintenance and positive isolation of media flow. For pipeline pig passage detection see the Stark Pig-Reporter passage indicator.
Engineered as a trunnion mounted ball valve in accordance with API 6D and ASME B16.34, this design allows pig launching and receiving within a compact footprint while reducing equipment, manpower, and downtime compared to traditional barrel and trap systems.
Estimated savings range from 25 to 60 percent over conventional systems.
