Parker Autoclave's 4B Series ball valves have been designed to provide superior quality for maximum performance within a variety of valve styles, sizes, and process connections. Some of the more unique design innovations include an integral one-piece trunnion mounted style ball and stem that eliminates
the shear failure common in two piece designs, re-torqueable seat glands that result in longer seat life, and a low friction stem seal that reduces actuation torque and enhances cycle life. These ball valves can also be modified to incorporate the use of special materials, seals for high temperature applications, subsea models, and valve actuators. When it comes to high-pressure applications, these ball valves
with associated high-pressure components, provide the critical performance demanded by the high pressure market.
