The pneumatic integral high-temperature ball valve is a valve design derived from the plug valve. Its opening and closing mechanism relies on a spherical component that rotates 90 degrees to complete the action. Due to its compact structure, ingeniously integrating the valve body, seat, and ball into one unit, it is called an integral valve.
● Strong High Temperature Tolerance: Made of special high-temperature resistant materials, it can withstand the working pressure in high-temperature environments, ensuring stable operation of the valve under high temperature conditions.
● Compact Structure and Easy Installation: Pneumatic integrated design, key components such as actuators and spheres are integrated together, compact structure, small space occupation, and simple and fast installation process.
● Superior Sealing Performance: The ball valve and valve seat adopt metal hard or soft sealing structures to ensure the sealing performance when the valve is closed, effectively preventing medium leakage.
● Flexible and Reliable Operation: Pneumatic actuators provide stable driving force, enabling valves to quickly respond to control signals, achieve quick opening and closing, and operate flexibly and reliably.

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?
After receiving the signal, the pneumatic device generates power through a cylinder or piston to rotate the valve stem. The valve stem is connected to the ball valve core, which rotates to drive the ball valve core. When the passage of the ball valve core aligns with the pipeline, the medium flows; when perpendicular, the medium is blocked. The valve is equipped with a sealing system to ensure high-temperature sealing performance. The sealing material is heat-resistant and wear-resistant, maintaining stable sealing effects at high temperatures. The valve design takes into account thermal expansion to ensure stability and reliability at high temperatures.
Our pneumatic integrated high-temperature ball valve is made from premium materials to ensure stable operation at high temperatures, with excellent heat and corrosion resistance. The valve is designed compactly for easy installation and maintenance, reducing fluid resistance and enhancing system efficiency. We offer a variety of specifications and configurations to meet different needs, ensuring the best solution is found. Our professional technical team and after-sales service system provide comprehensive support and maintenance, ensuring smooth production.
