Trunnion-mounted ball valves are pivotal components in fluid control systems, delivering precise regulation and robust sealing across diverse industries.

Distinct from other ball valves, trunnion ball valves boast a fixed ball securely anchored to a shaft, known as the trunnion, ensuring steadfast positioning. This innovative design offers exceptional stability and precise control, rendering trunnion ball valves exceptionally suitable for high-pressure applications.

Their fixed ball design provides superior sealing on both ends and necessitates minimal torque for operation, making trunnion ball valves the ideal choice for high-pressure scenarios.

Furthermore, the double block and bleed (DBB) process, which involves shutting off a pipe section on both sides of the valve, can be effectively executed with trunnion ball valves. They can block both upstream and downstream areas of the working zone and vent any residual pressure in the piping and valve, ensuring comprehensive control and safety.

ACEV trunnion-mounted ball valves are employed in the most demanding processes across virtually all industries.

Our extensive range features soft-seated designs that offer exceptional leak resistance, top-entry valves with a one-piece body for inline maintenance, and metal-seated valves that excel in high-temperature operations and provide robust abrasion resistance in challenging applications.

In addition to forged or cast bodies, welded body designs are perfect for buried service applications, minimizing potential leak points and reducing fugitive emissions from flanges.
