Are pneumatic actuators suitable for instrument panel mounting?
Pneumatic actuator is divided into double action and single action (spring reset), two cylinder, double piston, fork drive structure, easy to manufacture large cylinder, output torque, flexible and stable action; Hard chrome plating on inner wall and piston shaft, good wear resistance; All sliding components are equipped with oil-free lubricated bearings and guides to reduce friction coefficients and extend swing life. The U-shaped curve output torque of the pneumatic actuator is more suitable for large caliber ball valve, butterfly valve switch and adjustment, and can also be thrown to other 9O. Turn the occasion.
Functions and uses of pneumatic actuators and accessories
1. Double acting actuator: two position control valve switch.
2. Single function actuator (spring reset): circuit. Valve automatically closes in case of air path control or failure.
3. Double solenoid valve: one coil is energized when the valve opens, the other coil is energized when the valve closes, with memory function (explosion-proof type can be provided).
4, single electric control solenoid valve: the valve is open or closed when the power supply, the valve is closed or open when the power is off (explosion-proof type can be provided).
5. Limit switch returner: remote transmission of valve switch signal (explosion-proof type can be provided).
6 electrical positioner: according to the current signal (4-20) mA) control valve medium flow (explosion-proof type can be provided).
7 pneumatic positioner: according to the pressure signal (standard 0).02-0.1mpa) size of AW pneumatic valve medium flow control.
8. Electrical converter: convert current signal into pressure signal, and cooperate with pneumatic positioner (explosion-proof type can be provided).
9. Air source treatment triplet: including air pressure reducing valve. Filter. Oil mist device, stable air source. Clean. Lubricate moving parts.
10. Manual operation mechanism: under abnormal circumstances, the valve can be manually controlled.
