Full Welded Ball Valve: What is it

  • A fully-welded trunnion valve is a type of ball valve that is used to control the flow of gas or liquid through a passage. 
  • It is distinct from other ball valves because its ball is mounted and welded onto a trunnion at the base and supported by the stem at the top. 
  • All other components are also connected by welded joints.

Full Welded Ball Valve: Design Standard

  • Our fully-welded ball valves are available in sizes ranging from 2″ to 60″ with a full bore or reduced bore ball options. 
  • Each unit has an adjustable gland packing box with multiple stem sealing and thus provides control with zero leakage. 
  • Adhere to high-level API 6D and API 598 pressure test requirements as well as API 607/6FA fire safety standards.

Fully-welded Ball Valve: Industrial Applications

  • fully welded ball valve in petrochemical industry

A welded ball valve can be used to control the flow of oil products in oil refinery feedstock lines to avoid contamination of separate lines of products.

  • fully welded ball valve in chemical manufacturing

Due to their tight seal features, trunnion ball valves are ideal for safely managing corrosive chemicals after production.

  • fully welded ball valve in emergency shut-offs 

Quick to maneuver and provide a full-proof seal against the flow of media making them suitable for emergency system shut-off applications.

  • fully welded ball valve in power generation

Control the amount of power generated, the fuel has to be controlled as well. Trunnion ball valves control gas and liquid fuel flow very accurately.
