The integrated high-temperature ball valve is a type of valve evolved from a plug valve. Its opening and closing component is a sphere that rotates 90 degrees around the stem to achieve the function of opening and closing. This valve has a compact structure, integrating the valve body, seat, and ball into one unit. The ball in the integrated high-temperature ball valve is typically made of high-temperature resistant alloy material, capable of withstanding high-temperature and high-pressure working conditions, ensuring the valve's stability and reliability under high-temperature conditions. Additionally, it offers excellent sealing performance; the seat is made from special materials, effectively preventing medium leakage and ensuring safe system operation.
● Strong High Temperature Tolerance: Using high temperature resistant materials, it can cope with the working pressure in high temperature environments, ensuring stable operation of the valve in high temperature environments.
● Compact Structure and Easy Installation:The electrical integration design integrates the main components of the actuator and ball head together. The structure is small, takes up less space, and the installation process is simple and fast.
● Superior Sealing Performance: The ball and valve seat are sealed with hard or soft metal, ensuring excellent sealing effect when the valve is closed, effectively avoiding medium leakage.
