Trunnion Mounted Three Piece Ball Valve

Trunnion Mounted Three Piece Ball Valve About

FlowBiz Trunnion Mounted Ball Valves have their advantages over free-floating valves. The trunnion design provides a solution, and the ball does not float due to its connection with the Trunnion. It is advantageous since it will maintain a proper seal on both sides, and there is no added torque to the stem. Trunnion ball valves are suitable for low and high-pressure applications at very reasonable operational costs and offer lower operating prices than free-floating ball valves.

Advantages of the Trunnion Ball Design :

Ease of Operation.

Lower Operating Torque.

Minimised Seat Wear.

Premium Quality and Robust Design

Engineered with a trunnion-mounted stem, this three-piece ball valve offers superior support for the ball under high pressure, minimizing seat wear and enhancing operational longevity. The body is fabricated from high-grade carbon steel, stainless steel, or alloy steel, tailored to match various industrial requirements and fluid compatibilities.


Certifications and Safety Features

Every valve meets rigorous design and testing standards including API 6D, ISO 17292, and passes fire-safe tests per API 607 or ISO 10497. With blow-out proof stem construction and an integrated anti-static device, the valve ensures both regulatory compliance and user safety for peace of mind in critical operations.


Flexible Operation and Versatile Applications

Depending on process needs, the valve can be manually actuated with a lever or gear, or automated using pneumatic or electric actuators, facilitated by an ISO 5211 mounting pad. Its adaptability, wide temperature range (-29C to +200C), and variety of end connections make it suitable for pipelines handling water, oil, gas, and chemicals.
