What is an Audco Trunnion Mounted Ball Valve?
An Audco Trunnion Mounted Ball Valve is a quarter-turn valve in which the ball is mechanically supported by upper and lower trunnions. Unlike floating ball valves, the ball remains fixed while the seats move against it to create a tight seal. This design significantly reduces operating torque and provides reliable sealing even under high-pressure conditions.
Trunnion-mounted ball valves are widely used in large-diameter pipelines and critical process systems where dependable isolation, long service life, and safe operation are essential. Their robust construction ensures excellent performance in demanding industrial environments.
Why Choose Audco Trunnion Mounted Ball Valves?
Superior Sealing Performance
The trunnion-mounted design ensures tight shut-off by allowing spring-loaded seats to maintain consistent contact with the ball, minimizing leakage.
Low Operating Torque
The fixed-ball construction reduces friction, making valve operation smoother and requiring less actuator force.
Heavy-Duty Construction
Manufactured using premium-grade materials for superior strength, durability, and resistance to wear.
High Pressure Capability
Designed to perform reliably in high-pressure and high-temperature applications.
Fire-Safe and Anti-Static Design
Available with fire-safe certification and anti-static features to enhance operational safety in hazardous environments.
