Pneumatic threaded ball valves are ball valves controlled by pneumatic actuators, suitable for regulating and controlling media in pipelines. Their feature is the use of external thread connections, typically used in low-pressure, small-diameter pipelines. Pneumatic threaded ball valves consist of a ball, valve seat, sealing ring, stem, and pneumatic actuator. The ball has excellent sealing performance, ensuring no leakage of the medium.
● Easy Installation and Maintenance:Compact structure, small size, easy installation and maintenance. In limited space, the valve can provide effective fluid control to meet the needs of various complex working conditions.
● Superior Sealing Performance: Pneumatic internal thread ball valve has excellent sealing performance, using special sealing materials and structure, to ensure that the valve maintains good sealing effect under high pressure, high temperature or corrosive media, effectively prevent leakage.
● Easy Operation: Pneumatic actuators can quickly open and close valves, greatly improving work efficiency. At the same time, pneumatic actuators also have pressure loss safety function, when gas or power is lost, can automatically close or keep the valve in a safe position.
● Widely Application: The valve can be used in petroleum, chemical industry, natural gas, water treatment and other fields to meet the control needs of different media.

Q1:What is the main suitable of this valve?
This product is especially suitable for steel, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas and other media.
Q2:What mechanical principle is used?
The valve is primarily based on its unique structural design and the actuation method of the pneumatic actuator. The core component of the valve is a sphere with a through-hole that can rotate within the valve body. When the pneumatic actuator receives a control signal, it uses the power generated by the air source to drive the rotation of the sphere. The rotation angle of the sphere is typically 90 degrees. When the sphere rotates to align with the direction of the valve passage, the valve opens fully, allowing fluid to flow smoothly; when the sphere rotates to be perpendicular to the valve passage, the valve closes completely, blocking the flow of fluid.
