Pigging Ball Valve, 2 & 3 Piece, 2-36 Inch, Class 150-1500 LB

Pigging Valve

Pig valves are used to clean pipelines and improve transmission efficiency. Over time, impurities in the pipeline can block flow and reduce performance, so regular cleaning is necessary. Pig valves should be installed on pipelines that need frequent cleaning. Pigging valves look similar to ball valves. In fact, our pigging valves are based on our trunnion ball valves, sharing many features and functions. They are widely used in the oil and gas pipeline industry.

We also manufacture the following valves:

Full bore, Through-Conduit & Piggable design
Pig Valve, pigging valve, pigging ball valve, pig ball valve
Piggable Valve, Piggable ball valve
Pig Launcher and Receiver Valve
By-Pass Pigging Valves, Shut-Off Pig Valve, top entry pig valve
