About Trunnion Mounted Ball Valve

Trunnion ball valves are quarter-turn valves used to stop or start the flow of a media in a pipe. The most common type of ball valve has a free floating design, so the trunnion type is a design change. Within a trunnion ball valve the ball connects to the stem on one end and on the other end a shaft called the trunnion. Due to this design change, the ball is held firmly in place.

Advanced Design for Reliable Operation

Trunnion mounted ball valves are engineered for robust performance, featuring a fixed ball held by trunnions. This design minimizes torque and wear, enabling smooth movement even at high pressures. Whether you choose lever, gear, or actuator operation, these valves ensure reliable sealing for media ranging from water to chemicals, thanks to advanced soft (PTFE) or hard (metal) seat options. Their face-to-face dimensions comply with ASME B16.10, ensuring compatibility and easy installation.

Compliance and Safety Features

Every valve meets or exceeds stringent global standards including API 6D, BS5351, ISO 17292, and API 607 for fire safety. With API 598 and ISO 5208 testing protocols, users are assured of zero leakage and superior reliability. The inclusion of anti-static devices, blow-out proof stems, and optional double block & bleed setup increases safety for hazardous applications. Inspection certificates per EN 10204 3.1 guarantee full traceability for project assurance.

FAQ's of Trunnion Mounted Ball Valve:

Q: How is a trunnion mounted ball valve operated and what options are available?

A: Trunnion mounted ball valves can be operated manually via lever or gear, or automatically using pneumatic or electric actuators. Choice of operation depends on system requirement, size, and degree of automation needed.

Q: What standards and certifications do these ball valves conform to?

A: These valves are designed and tested in accordance with API 6D, BS5351, ISO 17292, API 598, ISO 5208, and feature fire-safe designs per API 607. Inspection certificates in EN 10204 3.1 are provided to ensure quality and compliance.

Q: Where are trunnion mounted ball valves typically used?

A: They are widely employed in industries like petrochemical, oil & gas, power plants, water treatment, and chemical processing, handling media such as water, oil, gas, and chemicals across varied pressures and temperatures.

Q: What is the process for ensuring valve reliability and leak-tight performance?

A: Each valve undergoes rigorous hydrostatic and leakage testing per API 598 and ISO 5208 to verify integrity and seat sealing. Fire-safe testing as per API 607 confirms operational safety even under fire conditions.

Q: When should I choose full bore versus reduced bore valve type?

A: Full bore valves offer unobstructed flow, ideal for pigging and minimizing pressure drop. Reduced bore valves are suitable for applications where flow rate reduction or cost efficiency is prioritized.

Q: What are the benefits of using forged steel or stainless steel body materials?

A: Forged steel and stainless steel provide excellent mechanical strength, corrosion resistance, and durability, essential for high-pressure, high-temperature, or corrosive media applications, offering prolonged service life.
