What is a Trunnion Gate Valve?

As the name implies, this gate valve incorporates a trunnion design. The latter provides stability to the ball, ensuring effective control of fluid or gas flow in a piping system.¹

For traditional floating ball valves, the ball is only supported by the valve stem. On the other hand, in the trunnion gate valve, this ball is anchored on both ends. The design primarily holds the ball firmly in place, even under high-pressure conditions. This explains why trunnion gate valves are ideal for larger, high-pressure applications, such as in the oil and gas industry.

How Does A Trunnion Gate Valve Work?

The working mechanism of a trunnion gate valve revolves around the controlled movement of a ball. It regulates the flow of media through a pipeline.² Here’s how it works:

1. Actuation: The valve is operated using an actuator. This component may be manual or electric.
2. Ball rotation: The actuator turns the valve stem. This is connected to the ball inside the valve. The trunnion at the opposite end stabilizes the ball.
3. Flow control: When the ball is rotated 90 degrees, the opening in the ball aligns with the pipeline. This allows the fluid to flow freely.
4. Closing the valve: To stop the flow, the actuator rotates the ball back by 90 degrees.
5. Sealing mechanism: The seat of the valve ensures the ball remains in position during rotation. As this occurs, it creates a tight seal that prevents leakage.

In conclusion, whether you choose a trusted name like Cameron or a high-quality manufacturer like PANS Valve, these manufacturers stand out. They are leaders in providing top-notch trunnion ball valves. Partnering with them will help your business provide the best service possible.
