High Temperature Ball Valve is a valve specifically designed for high-temperature environments, featuring excellent high-temperature resistance and sealing performance. Its operating temperature can reach approximately 600℃, and it is widely used in the oil, chemical, metallurgy, and hydropower industries.

Definition and Features

‌High-Temperature Resistance: The high-temperature ball valve operates stably in high-temperature environments, with a working temperature of about 600°C.‌

Excellent sealing: Offers various sealing types, including metal-to-metal sealing and stainless steel plate with graphite composite gasket to metal sealing, ensuring superior valve sealing performance.

Low fluid resistance: The sphere can be opened or closed by rotating 90 degrees within the medium, with minimal resistance during fluid passage.

Simple structure: fewer parts for easy installation, maintenance, and repair.

Working Principle

The high-temperature ball valve controls the flow of fluids through the opening and closing of the valve. When the valve is open, the ball rotates 90 degrees along the valve's axial direction, allowing the medium to pass through the ball's passage. When the valve is closed, the ball rotates another 90 degrees, sealing the passage of the ball against the valve's holes, thereby blocking the flow of the medium.

Application Areas

Petroleum Industry: Used for controlling the flow of high-temperature, high-pressure gases and liquids.

Chemical Industry: Control the flow of various acidic and alkaline media.

‌Metallurgy Industry: Widely used in the smelting processes of steel and non-ferrous metals.‌

Power Industry: Control the flow of media in equipment such as boilers and steam turbines in thermal power plants; control the cooling water and steam media in nuclear reactors in nuclear power plants.

Aerospace Industry: Meets requirements for high-temperature, high-pressure, and high-speed fluid control, with significant applications in aero-engine test stands, rocket launch pads, and similar venues.

‌Industry: Control the flow and transfer of various media in reactors, separators, and other equipment; regulate the filling and sealing of liquid media during pharmaceutical packaging processes.

Water Treatment Industry: Control the medium flow and pressure in water treatment equipment.

Maintenance and care

To ensure the normal operation and extend the service life of the high-temperature ball valve, regular maintenance is required. Specific measures include:

Regularly inspect the valve's sealing performance; if leakage is detected, replace the seal or perform maintenance promptly.

Lubricate and maintain pneumatic actuators, including cleaning and replenishing lubricating oil, to ensure their flexibility and stability.

Regularly clean the interior of the valve body to remove impurities and sediments, maintaining the cleanliness inside the valve body.
