Designed for Rugged Industrial Performance

These trunnion mounted ball valves are built for long-lasting, secure operation in critical industries. Their robust designs, including split body and fully welded types, comply with leading standards such as API 6D and ISO 17292. Enhanced with anti-static devices, fire-safe features, and blowout-proof stems, they ensure operational safety and reliability in even the harshest service conditions.


Versatility Across Media and Applications

From water and oil to corrosive acids and gases, these valves handle a wide spectrum of fluids at temperatures ranging from -29C to 200C. Their availability in carbon steel and stainless steel makes them ideal for applications in oil & gas, petrochemical, power generation, and water treatment, offering compatibility with ANSI, DIN, and JIS flange standards.

FAQ's of Trunnion Mounted Ball Valves:


Q: How do trunnion mounted ball valves enhance operational safety?

A: Trunnion mounted ball valves feature a blowout-proof stem, anti-static device, and API 607-compliant fire-safe design, protecting against stem dislodgement, static electricity build-up, and fire hazards. These safety mechanisms make the valves highly reliable for critical processes.

Q: What are the available operation types for these valves and how should one select among them?

A: Operation options include manual lever, gear operator, or automated actuator (pneumatic or electric). Select manual for smaller sizes or less frequent operation, gear for larger or high-torque applications, and actuators when remote or automated control is required.

Q: Where can trunnion mounted ball valves be installed effectively?

A: These valves are suitable for installation in oil & gas pipelines, petrochemical plants, power plants, and water treatment facilities. Stem extensions are available for underground service, ensuring reliable operation even below ground level.

Q: What is the benefit of choosing a split body versus a fully welded body valve?

A: Split body designs facilitate easier inspection and maintenance, while fully welded body valves provide enhanced leak-proof integrity without body flanges, beneficial for high-pressure or buried applications.

Q: How are these ball valves tested and certified?

A: Valves are tested in accordance with the API 598 standard for tightness and performance. Compliance with design standards like API 6D, BS 5351, and ISO 17292 ensures quality and reliability.

Q: What seat materials are available and how do they influence valve performance?

A: Seat options include PTFE, metal, and nylon. PTFE offers excellent chemical resistance, metal seats suit high-temperature or abrasive services, and nylon provides good mechanical strength and sealing at moderate temperatures.

Q: When should a customer consider optional coatings such as epoxy or FBE?

A: Optional coatings like epoxy, FBE, or custom finishes should be selected for corrosive environments or buried service, enhancing longevity and resistance to harsh conditions. Coated valves are especially recommended for aggressive industrial or outdoor applications.
