Ball Valve, Stainless Steel Ball Valve, Three-Piece Ball Valve

1. Description:

Three-piece ball valve is a widely used gas valve, with its own advantages, friction-free switch, seal will not be worn, opening and closing torque is small, the optional actuator is mainly compact type to achieve cutting off or adjusting the medium.

Now it is the first choice for gas equipment, petrochemical, aerospace, vacuum equipment, electroplating equipment, agricultural machinery, food machinery, iron and steel metallurgy, HVAC, drying equipment, biopharmaceutical, medical equipment, and other industries.

2. Specification:

3. Features:

• Fluid resistance is small, ball valve is one of the small fluid resistance of all valves, even the reduced diameter ball valve, its fluid resistance is quite small.
• Thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
• Sealing performance of the seat is good, the sealing ring made of polytetrafluoroethylene and other elastic materials, the structure is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure.
• Valve stem seal is reliable, because the valve stem is only as if rotating without lifting movement, the packing seal of the valve stem is not easy to destroy, and the sealing capacity increases with the pressure of the medium.
• Because polytetrafluoroethylene and other materials have good self-lubrication, and the friction loss with the ball is small, so the service life of the ball valve is long.
• Lower mounted valve stem and valve stem head convex step to prevent the valve stem ejecta, such as fire caused by the valve stem seal damage, the convex step and the valve body can also form metal contact to ensure the valve stem seal.
• Anti-static function: set a spring between the ball, valve stem and valve body, which can export the static electricity generated during the switching process .
