YT-1200R series Electro Pneumatic Positioner for pneumatic valve actuators​

The function and usage of the actuator and the parts

1. Double acting actuator: open and close the valve

2. Single acting actuator (Spring return ): when air or power is lost, the actuator either close the valve automatically or opens the valve automatically .

3. Double-control solenoid: power to solenoid opens the valve, power to the other solenoid closes the valve. This kind of solenoid possesses the memorial function (available for anti-exploding).

4. Limit switch box (signal feedback ):remotely passes the signal of the valve@s opened and closed status (available for anti-exploding).

5. Mechanical positioner: according to the air pressure to control the medium flux (available for anti-exploding).

6. Intelligent positioner:through the system set the valve position signal,and after the calculation process of the control software,and then control the pneumatic actuator of the intake and exhaust valve reaches the set point.

7. Manual equipment: able to use manual operation in the event of loss of air or power.

The feature of this product:

* Solid and Beautiful Design Aluminum Die-casting housing and powder coated.

* Boltson Visual Position Indicator Secure waterproof.

* Quick-Set Cam spring loaded splined cam No need to adjust again after initial setting Easy setting without tool.

* Multi point terminal strip Standard 8 point and enough strips for connection .

* Easy Mounting Namur standard stainless steel shaft and bracket.
