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, which completes the action of opening or closing by rotating 90 degrees. This type of valve is called an integral one because of its compact structure, ingeniously integrating the valve body, seat, and ball into a single unit.
● Strong High Temperature Tolerance: Made of special high temperature resistant materials, can withstand the working pressure in high temperature environment, to ensure the stable operation of the valve under high temperature conditions.
● Compact Structure and Easy Installation: Pneumatic integrated design, the key components such as actuator and sphere are integrated into one, compact structure, small space occupation, simple and quick installation process.
● Superior Sealing Performance: The ball and valve seat are made of metal hard or soft sealing structure to ensure the sealing performance under the closed state of the valve and effectively prevent the leakage of media.
● Flexible and Reliable Operation: The pneumatic actuator provides a stable driving force, so that the valve can quickly respond to the control signal, achieve rapid opening and closing, flexible and reliable operation.

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, causing the valve stem to rotate. The valve stem is connected to the ball valve core, and its rotation drives 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 at high temperatures. The valve design takes into account thermal expansion to ensure high-temperature stability and reliability.
Our pneumatic integrated high-temperature ball valve use premium materials to ensure stable operation at high temperatures, featuring heat resistance and corrosion protection.
