Pneumatic Casting Trunnion Ball Valve

Middleeast Valve is Leading Exporter of Pneumatic Casting Trunnion Ball Valve. We proudly supplies high performance Pneumatic Casting Trunnion Ball Valve, built for demanding industrial applications that require reliable sealing and automated control under high pressure. These valve combine robust cast body construction with a trunnion mounted ball design and pneumatic actuation for smooth and efficient operation.

 Definition

A Pneumatic Casting Trunnion Ball Valve is a heavy duty quarter turn valve that use a pneumatic actuator for automatic operation. The ball is supported by trunnions, reducing torque and ensuring tight sealing even under extreme pressure. The cast body provides structural strength and durability in tough environments.

 Key Parts

  1. Valve Body: Made from cast carbon steel, stainless steel or alloy material.
  2. Trunnion Mounted Ball: Fixed and supported ball design reduces operating torque.
  3. Seats and Seals: Often spring loaded for consistent sealing under pressure.
  4. Pneumatic Actuator: Uses compressed air for remote, automatic valve operation.
  5. Stem and Bearings: Ensure smooth rotation and reduce wear over time.

 Working Mechanism

Compressed air powers the actuator to rotate the stem and ball 90 degrees, opening or closing the valve. The trunnion design anchors the ball in place, while pressure-energized seats maintain a tight seal regardless of flow direction or system pressure.

 Advantages

  • Suitable for high-pressure and high-temperature environments
  • Reduced operating torque and energy use
