The Underground ASTM A105 Fully Welded Ball Valve (DN600 PN40) is a high-integrity isolation valve specifically engineered for buried service in gas or oil networks. The fully welded forged body eliminates external leak paths, while the PN40 rating supports high-pressure transmission. It features a trunnion-mounted ball for low torque and is typically equipped with a stem extension and specialized anti-corrosive coating to allow for reliable surface operation from a buried position.
