Pneumatic threaded ball valve is a type of ball valve controlled by pneumatic actuators, suitable for controlling and regulating the medium inside pipelines. Its characteristic is the use of external thread connection, usually used for low-pressure, small-diameter pipelines. Pneumatic threaded ball valve consists of a ball, a valve seat, a sealing ring, a valve stem, a pneumatic actuator, etc. Its sphere has good sealing performance, which can ensure that the medium does not leak.
● Easy Installation and Maintenance: Compact structure, small size, easy installation and maintenance. In a limited space, this valve can provide effective fluid control and meet the needs of various complex working conditions.
● Superior Sealing Performance: Pneumatic internal thread ball valves have superior sealing performance, using special sealing materials and structures to ensure that the valve maintains good sealing effect under high pressure, high temperature or corrosive media, effectively preventing leakage.
● Easy Operation: The valve can be quickly opened and closed by a pneumatic actuator, greatly improving work efficiency. At the same time, pneumatic actuators also have a fail safe function, which can automatically close or keep the valve in a safe position when gas or power is lost.
● Widely Application: This 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?
This valve is mainly based on its unique structural design and the driving method of the pneumatic actuator. The core component of a valve is a ball with a through-hole that can rotate inside the valve body. When the pneumatic actuator receives a control signal, it uses the power generated by the air source to drive the ball to rotate. The rotation angle of a sphere is usually 90 degrees. When the sphere rotates to align with the direction of the valve flow path, the valve fully opens, allowing fluid to pass smoothly; When the sphere rotates to a flow path perpendicular to the valve, the valve is completely closed, completely blocking the fluid.
Our pneumatic internal thread ball valve has excellent flow control capability, which can meet the precise fluid control requirements of various processes, thereby improving product quality. The optimized design reduces fluid resistance, lowers energy consumption, and meets environmental standards, supporting the company to achieve green production. We offer a variety of specifications and configuration options to meet the needs of different application scenarios and provide customized solutions. Our professional technical team provides comprehensive pre-sales consultation, installation and commissioning, as well as after-sales service to ensure worry free use for customers.
