Pneumatic Ball Valve is a valve device that uses compressed air to drive an actuator to control the rotation of a ball to start, stop or adjust the material flow. It is widely used in pneumatic conveying systems to accurately control the flow of gas or dry bulk materials (such as powders, granules, etc.). Pneumatic ball valves play an important role in ensuring the stable operation of the system with their fast response, high sealing and reliability.
The working principle of the pneumatic ball valve is based on its structural design and the operation of the pneumatic actuator:
Ball and seat: The ball is located in the valve body and has a hole through its center. When the ball rotates, the hole can be aligned or staggered with the pipe, thereby opening or closing the channel.
Pneumatic actuator: driven by compressed air, pushes the ball to rotate 90 degrees to complete the switching action. Actuators can be single-acting (spring return only) or double-acting (bi-directional pneumatic control).
Sealing mechanism: A sealing ring made of elastic material is used between the ball and the valve seat to ensure complete prevention of medium leakage in the closed state; at the same time, wear-resistant liners are provided on both sides of the valve body to reduce friction between the ball and the valve seat.
Locking device: Some models are equipped with a mechanical locking device to prevent accidental opening or closing for added safety.
When the material flow needs to be controlled, the control system sends a signal to the pneumatic actuator, which drives the ball to rotate according to the instructions, thereby opening or closing the material channel. This non-contact driving method not only improves response speed, but also reduces mechanical wear and extends service life.

Quick response: Due to the use of pneumatic actuators, pneumatic ball valves can complete the switching action in a short time and respond quickly.
High sealing: The special sealing design ensures zero leakage in the closed state, ensuring the air tightness and material integrity of the system.
Wear-resistant and durable: Made of high-quality materials to extend service life and reduce maintenance costs.
Low torque requirements: Compared with other types of valves, pneumatic ball valves require less switching torque, reducing the load on the actuator.
Strong adaptability: It can handle various types of materials and is not affected by the humidity and viscosity of the materials. It is especially suitable for fragile or sensitive materials.
Safe and reliable: Equipped with multiple protection mechanisms, such as overload protection, short circuit protection, etc., to ensure the safety of personnel and equipment.
Easy to install and maintain: The compact design makes it easy to integrate into existing pipelines and facilitate maintenance.
Products are widely used in petroleum, chemical industry, water treatment, sewage, papermaking, water conservancy project construction and other industrial fields
