Integrated high-temperature ball valve is a type of valve evolved from a plug valve. The opening and closing component is a sphere that rotates 90 degrees around the axis of the valve stem to achieve opening and closing. This type of valve has a compact structure, integrating the valve body, seat, sphere, and other components together to form a whole, hence it is called an integrated type.
● 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:The electric integrated design integrates key components such as actuator and ball head into one, compact structure, small space occupation, simple and quick installation process.
● Superior Sealing Performance: The ball and the valve seat are made of metal hard or soft sealing structure, which ensures good sealing performance of the valve in the closed state and effectively prevents medium leakage.
