Middle East Valve is one of the leading Trunnion Ball Valve Suppliers in Saudi Arabia, delivering high-performance valves to cities such as Hatta, Zayed, and Al Aweer. Trunnion-mounted ball valves are widely used in oil & gas, water treatment, and chemical industries, where dependable sealing and high-pressure capabilities are essential.

What is a Trunnion Ball Valve?

A trunnion ball valve features a spherical ball supported by trunnions at both the top and bottom. Unlike floating ball valves that rely on line pressure to seal, the trunnion design anchors the ball securely, making it suitable for large sizes and high-pressure systems.

· Open Position – The ball aligns with the pipeline, providing unobstructed flow.

· Closed Position – A 90° turn blocks the passage, ensuring a secure seal.

· Trunnion Support – Minimizes wear, reduces torque, and enhances sealing performance.

Trunnion Ball Valve vs Floating Ball Valve

· Trunnion Ball Valve – Anchored ball with reduced movement, designed for heavy-duty, high-pressure applications. Offers long-term durability and tight shut-off.

· Floating Ball Valve – The ball floats between two seats, suitable for low to medium pressure applications. Compact and economical but less suited for extreme conditions.

Benefits of Trunnion Ball Valves

· Low operating torque for smooth handling

· Reduced seat wear, extending valve service life

· High resistance to pressure and temperature extremes

· Excellent sealing performance with minimal leakage

· Bidirectional flow capability for flexible operation

· Compact design, requiring less installation space

Key Components

· Ball – Precision-engineered, usually stainless steel or alloy, for flow control.

· Trunnions – Provide top and bottom support, enabling stable ball rotation.

· Seats & Seals – PTFE or metal, ensuring tight shut-off under pressure.

· Actuator/Handle – Can be manual or automated with pneumatic, hydraulic, or electric systems.
