Parker Autoclave Engineers high-pressure 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 the associated high-pressure components, provide the critical performance demanded by the high pressure market.


  • One-piece, trunnion-mounted style, stem design eliminates shear failure and reduces the effects of side-loading found in two-piece designs.
  • Re-torqueable seat glands for longer seat life.
  • PEEK seats offer excellent resistance to chemicals, heat, and wear/abrasion.
  • Full-port flow path minimizes pressure drop.
  • 316 cold-worked stainless steel construction.
  • Low friction pressure-assisted graphite-filled PTFE stem seal increases cycle life and reduces operating torque.
  • Quarter-turn from open to close with positive stop.
  • Viton o-rings
  • Wide selection of tube and pipe end fittings


  • Optional o-ring materials for high-temperature applications.
  • Optional wetted materials.
  • Electric or pneumatic actuators
