Forged 3 Piece Trunnion Ball Valves for the Petrochemical Industry
RGR purpose designs and manufactures series PC valves for high cycle switching and severe on-off applications. The stem to ball union is based on our unique “flower drive” design and has proven to be reliable even under severe service conditions. Depending on the application, the flow paths through the ball and seats may be altered to guarantee the best performance of the valve package in a particular process.
