Pig Launcher Valve

Main Features:

Pigging Ball Valve is a new concept for pigging launcher or pigging receiver, mainly used to cleaning pipe in gas gate station, sweeping pipe and cleaning short-distance pipe. Applicable in oil and gas field, oil-gas gathering and transportation, oil-gas storage, chemical terminal, chemical reservoir, off-shore oil platform and other pigging operation in fluid transportation pipelines.
Pigging Ball Valve is the pipeline construction, cleaning, maintenance, testing and management of essential equipment, the use of pigging valve and with the appropriate pipeline pig, Pipeline cleaning, emptying, separating, sequential transportation of medium and inspection can be easily accomplished.
Pigging Valves contain pigging launcher and pigging receiver, they are paired. And by using the compatible pig. pigging valve can completely replace the complex conventional device for launching pig and receiving pig.
