Parker Autoclave's high-pressure ball valves have been designed to provide superior quality for maximum performance within a variety of valve styles, sizes, and process connections. Our unique design innovations include an integral one-piece trunnion mounted ball and stem that eliminates the shear failure common in two piece designs, re-torqueable seat glands that result in longer seat life, and lower friction stem seal that reduces actuation torque and enhances cycle life.
