The main characteristic of pneumatic high-pressure pneumatic valve and the suitable areas

Pneumatic high-pressure pneumatic valve it has rotated 90 degrees, the cock body to body, a circular hole or channel through its axis. Pneumatic valve in the pipeline is mainly used for cutting, distribution, and change the flow direction of medium, the operation of the rotated 90 degrees and small rotational torque can be closed tightly. Pneumatic valve suitable for switch, cut off the pneumatic valve is used, but recent development has pneumatic valve designed to make it with throttling and control flow, such as V pneumatic valve. Pneumatic V pneumatic valve is a quarter-turn structure control pneumatic valve, pneumatic valve can be divided into pneumatic V adjusted and pneumatic V cut off the pneumatic valve. It with pneumatic valve positioner, proportional control can be realized.

high pressure pneumatic valve itself is the main characteristics of compact structure, good sealing, simple structure, convenient maintenance, and facial sealing surface often in the closed state, not easily be medium erosion, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, has been applied in many industries. Pneumatic valve pneumatic valve can be integral, also can be combined. The form of pneumatic valve body integral forging pneumatic valve body ( (2) , a three-stage forging pneumatic valve body ( (the above) , connection flange type, welding type, screw type ( Suitable for PN45MPa) Pneumatic valve core, adopting O body, flow characteristic of approximate quick opening characteristics.


pneumatic high-pressure pneumatic valve pneumatic valve rod drives the pneumatic valve core in the pneumatic valve body rotate 90 ° can achieve full open - Full close action. Can adopt intelligent control and positioning, and form a complete set of electric pneumatic valve positioner, enter 4 20 madc signal and 0. 4 to 0. 7 mpa air can control operation, realize the parameters such as pressure, flow, temperature, liquid level adjustment. Q611 pneumatic high-pressure pneumatic valve according to its sealing property is divided into metal seal and soft seal. Pneumatic high-pressure pneumatic valve has a compact structure, small volume, smooth operation, good sealing, easy maintenance, easy installation, etc. Pneumatic high-pressure pneumatic valve is suitable for medium thick, containing particles, the occasion of fiber properties. Pneumatic high-pressure pneumatic valve is mainly used in petroleum, chemical industry, teaching equipment, light industry, high pressure equipment, paper and other industrial automatic control system, the long-distance centralized control and local control.
