Ball Valves mounted over a ball, also called Trunnion Ball Valves are mainly used in the petroleum industry; extraction and refinement of products like oil and natural gas. These valves provide confidence in service given their double blockage and purge function.

The engineering development of WALWORTH products is bound to API 6D, ISO 14313, ASME B16.34 and ASME VIII standards. Different classes of pressure are available, from 150 to 2500, and can be manufactured in though conduit or piggable. The later facilitates the pass of cleaning and calibration tools for pipe systems. Also, it avoids turbulence and pressure drops.

  1. Carbon steel (A 105 – WCB)
  2. Carbon steel (low temperature) (LF2, LF3 – LCB, LCC)
  3. Stainless steel (F316, F347 – CF8M, CF8C)
  4. Duplex steel (F51 – CD3MN)
  5. Super duplex stainless steel (F55 – CD3MWCuN)

Special materials can be used if the fluid and service require it.

Walworth interior arrangement for Trunnion ball valves includes all the materials in the “Trim” section of the document: API-6D standard. High tension resistant materials such as 17-4pH steel, duplex steel, super duplex steel (UNS S31803, UNS S32750), and high alloys like Monel, Inconel and Incoloy are also available.

Thermoplastic elastomers such as: Viton, PTFE, NYLON, DEVLON, and PEEK are available and are used as soft inserts. The choice will depend on the temperature, pressure, and type of fluid that the valve will manage. Special inserts are also available.
