Product Overview
The electrically non-magnetic fixed-type The electrically non-magnetic fixed-type ball valve can be controlled by a valve positioner input signal source (4-20mADC or 1-5V0) to start and stop the operation.ball valve can be controlled by a valve positioner input signal source (4-20mADC or 1-5V0) to start and stop the operation. It can also be controlled by an electric actuator.It can also be controlled by an electric actuator. The pneumatic valve can be controlled by a travel limit switch, an electromagnetic valve, a three-way valve, and an 0. The pneumatic valve can be controlled by a travel limit switch, an electromagnetic valve, a three-way valve, and an air source of 0.4-0.4-0.7MPa air source to achieve on-off operation, and two pairs of passive contact signals will be sent to indicate the valve's on-off status.7MPa to achieve on-off operation, and two pairs of passive contact signals will be sent to indicate the valve's on-off status. It is widely used in automation control systems of industrial departments such as papermaking, petrochemicals, chemicals, metallurgy, power, environmental protection, petroleum, and light industry.
Structural Features
It is widely used in automation control systems of various industrial departments such as papermaking, petrochemicals, chemicals, metallurgy, power, environmental protection, petroleum, and light industry.
1.Structural Features
1. Low fluid resistance: The ball valve is one of the valve types with the lowest fluid resistance. Low fluid resistance: The ball valve is one of the valve types with the lowest fluid resistance. Even for a reduced-diameter ball valve, the fluid resistance is still quite low.
2. Even for a reduced-diameter ball valve, the fluid resistance is still quite low.
2. Reduced friction torque of the thrust bearing: The thrust bearing reduces the friction torque of the valve stem, enabling the valve stem to operate smoothly and flexibly for a long time.
3. Reduced friction torque of the thrust bearing: The thrust bearing reduces the friction torque of the valve stem, enabling the valve stem to operate smoothly and flexibly for a long time.
3. Good valve seat sealing performance: The sealing ring is made of elastic materials such as polytetrafluoroethylene. Good valve seat sealing performance: The sealing ring is made of elastic materials such as polytetrafluoroethylene. The structure is easy to seal, and the valve seal capacity of the ball valve increases with the increase of the medium pressure.
4. The structure is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure.
4. Reliable valve stem sealing: Since the valve stem only rotates without lifting, the packing seal of the valve stem is less likely to be damaged, and the sealing capacity increases with the increase of the medium pressure.
5. Reliable valve stem sealing: Since the valve stem only rotates without lifting, the packing seal of the valve stem is less likely to be damaged, and the sealing capacity increases with the increase of the medium pressure.
5. Long service life due to good self-lubrication of materials such as polytetrafluoroethylene, with low friction loss between the ball and the ball body, so the service life of the ball valve is long.
6. Long service life due to good self-lubrication of materials such as polytetrafluoroethylene, with low friction loss between the ball and the ball body, so the service life of the ball valve is long.
Bottom-mounted valve stem and valve stem head protrusion prevent the valve stem from spraying out.6. Bottom-mounted valve stem and valve stem head protrusion prevent the valve stem from spraying out. In case the valve stem seal is damaged due to a fire, the protrusion can form metal contact with the valve body to ensure the valve stem seal.
7. In case the valve stem seal is damaged due to a fire, the protrusion can form metal contact with the valve body to ensure the valve stem seal.
7. Anti-static function: Springs are set between the ball, the valve stem, and the valve body to guide the static electricity generated during the switching process out. Anti-static function: Springs are set between the ball, valve stem, and valve body to conduct the static electricity generated during the switching process.
The pneumatic stainless steel fixed ball valve can be controlled by connecting a valve positioner input control signal (4-20mADC or 1-5V0) source. This pneumatic ball valve can also be equipped with travel limit switches, solenoid valves, three-way valves and 0.4-0.7MPa air source to achieve on-off operation and send out two pairs of passive contact signals to indicate the valve's opening and closing status. It is widely used in the automation control systems of industries such as papermaking, petrochemicals, chemicals, metallurgy, power, environmental protection, petroleum, and light industry.
Packing of Standard Packing:
