Pneumatic threaded ball valve is a ball valve controlled by a pneumatic actuator, suitable for controlling and adjusting the medium inside the pipeline. Its characteristic is the use of external thread connection, which is usually used for low-pressure, small diameter pipelines. Pneumatic threaded ball valve is composed of a ball, valve seat, sealing ring, valve stem, pneumatic actuator, etc. Its sphere has good sealing performance, which can ensure that the medium does not leak.
● Easy Installation and Maintenance: It has a compact structure, small volume, and is easy to install and maintain. In a limited space, this valve can provide efficient fluid control and meet the needs of various complex working conditions.
● Superior Sealing Performance: Pneumatic internal thread ball valve has superior sealing performance, using special sealing materials and structures to ensure that the valve can maintain good sealing effect under high pressure, high temperature or corrosive media, effectively preventing leakage.
● Easy Operation: The valve can be quickly opened and closed through a pneumatic actuator, greatly improving work efficiency. At the same time, pneumatic actuators also have a fail safe function, which can automatically close or maintain the valve in a safe position when the gas or power source is lost.
● Widely Application: The valve can be used in various fields such as petroleum, chemical, natural gas, water treatment, etc., 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 drive method of the pneumatic actuator. The core component of the valve is a sphere with a through-hole, which can rotate within the valve body. When the pneumatic actuator receives a control signal, it drives the sphere to rotate using the power generated by the air source. The rotation angle of the sphere is typically 90 degrees. When the sphere rotates to align with the direction of the valve's flow path, the valve is fully open, allowing fluid to pass smoothly; when the sphere rotates to be perpendicular to the valve's flow path, the valve is fully closed, completely blocking the fluid.
Our pneumatic internal thread ball valve boasts excellent flow control capabilities, capable of meeting the precise fluid control requirements of various processes, thereby enhancing product quality. The optimized design reduces fluid resistance and lowers energy consumption while complying with environmental standards, supporting companies in achieving green production.
