Pneumatic track ball valves are fluid control devices that integrate the structural features of pneumatic actuators and track ball valves. They operate by using compressed air to rotate the ball within the valve body for opening or closing, while optimizing the movement path with track design. Their core advantages include rapid switching (as fast as 0.05 seconds per operation), low fluid resistance, and compact structure, making them suitable for high-pressure, high-temperature, and corrosive medium environments.
Working Principle
The pneumatic track ball valve receives compressed air power through a pneumatic actuator, driving the ball to rotate 90 degrees around the valve body centerline to complete the on/off action. It opens when the ball passage aligns with the valve body's inlet and outlet, and closes when the passage becomes vertical after rotating 90 degrees. Its track design minimizes movement deviation, enhancing control accuracy.
Structural Features
Sphere Type: Floating Sphere, Fixed Sphere, or Elastic Sphere Structure, suitable for various pressure scenarios
Material Options: Carbon steel, stainless steel, plastic, etc., to meet corrosion resistance or high-temperature requirements
Sealed Design: Metal or rubber sealing surface for long-term stability
Application Scenario
Suited for the petrochemical, power, and other fields, it excels particularly in pipeline systems requiring rapid shutdown or adjustment of fluids. For example:
Rapid switch control for natural gas transmission pipelines
Transportation and distribution of corrosive liquids (such as acids, alkalis)
