A pneumatic threaded ball valve is a type of ball valve controlled by a pneumatic actuator. It is suitable for regulating and controlling media in pipelines. Its unique feature lies in the use of external threaded connections, making it commonly applicable to low-pressure and small-diameter pipeline environments. The valve consists of key components such as the ball, seat, seal ring, stem, and pneumatic actuator. The ball section boasts excellent sealing performance, ensuring airtightness during the transmission of media and preventing leaks.

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 design of the valve is based on its unique structure and the drive mechanism of the pneumatic actuator. Its core component is a sphere with holes that can rotate freely inside the valve body. When the pneumatic actuator receives a control signal, it uses the power supplied by an air source to drive the rotation of the sphere. The rotation angle of the sphere is typically 90 degrees. Once the sphere rotates to align with the valve passage, the valve opens fully, ensuring smooth fluid flow; conversely, when the sphere rotates to be perpendicular to the valve passage, the valve closes completely, effectively blocking the flow of fluid.
Our pneumatic internal thread ball valve boasts superior flow control performance, capable of meeting the stringent requirements for precise fluid control in various process flows, thereby enhancing product quality. Through optimized design, we have significantly reduced fluid resistance, lowered energy consumption, and met environmental standards, supporting companies on their journey towards green production. We offer a variety of specifications and configuration options to meet the needs of different application scenarios, providing customized solutions. Additionally, we have a professional technical team that can offer comprehensive pre-sales consultation, installation and commissioning, as well as after-sales service, ensuring worry-free use for our customers.
