Parker MAB series manual, pneumatic and electrically actuated two-way and three-way ball valves are designed for quarter and half turn media shutoff or switching applications up to 15,000 psi. Our single-piece trunnion style ball design and re-torqueable seats make the MAB series ideal for severe service applications. The end connector design enables a variety of end connections and combinations for specific customer applications. Please see Parker Autoclave Engineers Ball Valve Literature for additional connection options.
