    The pneumatic ball of applications and features

    Category:Industry News Publish:2013/1/8 15:57:49 Browse:1466 [Back]
    Shen high pneumatic ball valve configured by the ball valve pneumatic actuators, pneumatic actuators into a double acting pneumatic actuators and single-acting pneumatic actuator, controlled by a solenoid valve, ball valve switching action. Pneumatic ball valves intelligent control to quickly turn on or off the pipeline, which can effectively control and management of pipe network.
    The ball valve in the pipeline is mainly used for cutting, assigning and changing the direction of flow of the medium, it requires only rotated by 90 degrees of operation and a small rotational torque can be closed tightly. The most suitable valve switch, use the shut-off valve, but the recent development has been the ball valve designed to give it throttle and control the flow, such as V-ball valve.

    Shen high pneumatic ball valve applications:
    Ball valve itself compact structure, reliable sealing, simple structure, easy maintenance, the spherical surface and seal often in the closed state, is not easy to be medium erosion, easy operation and maintenance, general working media applies to water, solvents, acids, and natural gas, but also applicable to the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene in various industries has been widely used. Ball valve can be a whole, it can be modular.

    Shen the high pneumatic ball valve characteristics:
    Pneumatic ball valve is mainly used for cut off or turned on the line of media can also be used for fluid regulation and control, pneumatic ball valves and other valve types compared with the output torque of the angular travel, open the quick, smooth and reliable, widely applicable, etc. The following advantages.

    1 small fluid resistance, the pneumatic ball is the smallest one of all valves classification fluid resistance, even necking pneumatic ball valve, the fluid resistance is quite small.
    Thrust bearing reduce stem friction torque, can stem the long-term operation is smooth and flexible.
    3, the valve seat sealing performance, the use of the sealing ring made of elastic material such as polytetrafluoroethylene, the structure is easy to seal, and the pneumatic ball valve sealing ability is increased with increasing pressure of the media.
    Stem seal reliably do lifting movement due to The stem for imitation rotation shipped without filler valve stem seals not easy to destroy, and sealing ability increases with increasing media pressure.
    Teflon and other materials have good self-lubricating, loss of friction with the ball, so the long service life of pneumatic ball.
    6 Bottoms-stem and stem head convex order to prevent the stem spray, such as a fire caused by the stem seal damage, also form a metal-to-metal contact between the convex order with the valve body, to ensure that the valve stem seals.
    7, anti-static function: ball, stem, the valve body between spring and the electrostatic Export able to switch process.
