Components of a Trunnion Ball Valve

A trunnion ball valve is a must-have in many industries. It includes multiple parts that work together for optimal performance. These pieces are the body, seats, stem, balls, seals, and actuators. Let’s explore each one:

  1. Body: The outermost part of the valve which encases all the internal components.
  2. Seats: Present inside the valve body, they keep the ball from leaking when it’s closed and form a tight seal when it’s open.
  3. Stem: Connects the actuator or handle to the ball. This piece helps rotate/pivot the ball within the valve’s body.
  4. Balls: Trunnion ball valves have two – an upper & lower ball. These spheres facilitate closing/opening and regulate flow.
  5. Seals: Essential for leak-free operation, these are usually made of PTFE (Polytetrafluoroethylene) or elastomers.
  6. Actuators: Devices used to automate the valve’s operation. They can be electrical, hydraulic, or pneumatic.

Trunnion ball valves may also feature additional accessories like positioners and limit switches. These valves are used in various industries, such as oil/gas, petrochemicals, power plants, and water treatment plants.

Tip: When selecting a trunnion ball valve, think about pressure rating, material compatibility, and your system’s specific requirements for optimal performance & longevity.

Working Principles of a Trunnion Ball Valve

A trunnion ball valve has a unique working principle. It consists of a ball with a hole in the middle, held in place by two trunnions at opposite ends. When closed, the ball spins to block flow. When open, it rotates to let fluid through.
