Trunnion-Mounted Ball Valves: Design & Operation
A trunnion mounted ball valve is a type of valve commonly used in fluid control processes due to its robustness and reliable performance. The valve utilizes a spherical rotor that rotates within a cavity to regulate the flow of liquids. The trunnion, a shaft, is mounted to the ball, allowing for smooth and efficient rotation. This design ensures minimal resistance during operation, contributing to the valve's longevity and efficiency.
- Critical aspects of a trunnion mounted ball valve include:
- High-quality components for withstanding extreme pressures
- Precise control
- Low torque requirements
These valves are available in a range of sizes and materials to suit multiple industries.
