Pneumatic threaded ball valve is a type of ball valve controlled by pneumatic actuators, suitable for regulating and controlling media in pipelines. Its uniqueness lies in the use of external thread connections, which are typically suitable for low-pressure and small-diameter pipeline environments. This valve consists of key components such as a ball, valve seat, sealing ring, valve stem, and pneumatic actuator. The spherical part has excellent sealing performance, which can ensure the sealing of the medium during transmission and prevent leakage.
● High Efficiency:The pneumatic internal thread ball valve adopts advanced design to ensure fast and accurate fluid control and improve production efficiency.
● High Quality Materials:High quality stainless steel and alloy materials are used to ensure the stable operation of the valve in various harsh environments and prolong the service life.
● Easy to Maintain: The structural design is reasonable, easy to disassemble and clean, reducing maintenance costs and downtime.
● Safe and Reliable: Through strict testing and quality control, the valve is ensured to be safe and reliable in high-pressure and high-temperature environments, ensuring production safety.

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 actuator. The core component is a sphere with holes that can rotate freely within the valve body. When the pneumatic actuator receives a control signal, it uses the power provided by the air source to drive the sphere to rotate. The rotation angle of the sphere is typically 90 degrees. Once the sphere rotates to align with the valve passage, the valve opens fully to ensure smooth fluid flow; conversely, when the sphere rotates to be perpendicular to the valve passage, the valve closes completely, effectively blocking fluid flow.
Our pneumatic internal thread ball valve has excellent flow control performance, which can meet the strict requirements for precise fluid control in various process flows, thereby improving product quality. By optimizing the design, we have significantly reduced fluid resistance, lowered energy consumption, met environmental standards, and supported enterprises in transitioning to green production. We offer various specifications and configuration options to adapt to different application scenarios, and provide customized solutions. In addition, we have a professional technical team that can provide comprehensive pre-sales consultation, installation and commissioning, as well as after-sales service to ensure that customers can use our products with confidence.
