Product Description

The hard seal high-temperature ball valve adopts an eccentric structure, and the sealing specific pressure between the valve seat and the ball cold increases rapidly during the closing process, thus ensuring the reliable sealing of the sealing pair. When the valve is opened, the valve seat and the ball can be quickly separated, which effectively reduces the operating torque and minimizes the possibility of damage control between the valve seat surface and the spherical surface.



It can be used in both directions and is not easy to deposit dirt in the middle cavity.
The surface is specially hardened to ensure that there is a suitable hardness difference between the sealing pairs.
Particularly suitable for solid particles and abrasive media.
It can be used for high temperature and high pressure working conditions, and has the function of fire resistance.

A ball valve has 7 essential parts that make up its structure:

• Body and cover (3): These are the pressure retaining parts, being the container for the internal parts of the valves. The body is where all the parts are assembled.
• Ball (4): It is the element located in the flow passage that allows (or prevents) the flow inside the line, through a 90º turn on an axis perpendicular to the flow direction.
• Stem (1): This is the element that actuates the ball, and can be manually or automatically operated (electrically or pneumatically).
• Handle: This is the lever that allows the ball to be operated through the stem.
• Seats (5): These components, made of different materials, are positioned to hold the ball between the sealing surfaces of the seat itself, thus allowing the fluid to be hermetically sealed.
• Body seals: These are the elements that prevent fluid leakage to the outside between the body and the valve cover. They can be made of various materials.
• Valve stem seals (2): Valve stem seals are the sealing elements that are placed between the valve body and the valve stem to prevent leakage of fluid to the outside. They can be made of different materials.
