Tight shutoff is essential during oil and gas applications, and the superior anchoring of the PBV® trunnion-mounted ball valves make them especially well-suited for large, high-pressure valve applications. To reduce torque even at high operating ranges, the trunnion-mounted stems absorb line pressure and minimize friction between balls and seats. PBV valves are manufactured with all three-piece and two-piece trunnion ball valves to the highest engineering and quality standards.
