Description


Piston Actuator

F79U/E/D pneumatic actuators double-acting (air to air) and single acting (spring reset), 90 ° pneumatic operation 


Main features

1) Compact gear rack design, double piston big torque

2) The output of this  cylinder actuator

The single-piece piston rack drive can reduce the dynamic seal quantity, make the air leak to a  minimum

3) Double piston design eliminates the lateral negative on the gear shaft , so that the bearing wear to a minimum

4) Spring using epoxy paint and color coding, not only anti-corrosion effect, but also easy to identify

5) Anode aluminum shell, and the external ESPC surface treatment, can prevent external corrosion caused by salty air, etc

6) Surface treatment: chemical nickel plating

7) Hollow output drive shaft can be directly assembled in some applications to avoid the special connection, and ensure correct alignment

8) To insert the piston friction pad at the bottom of the gear shaft ensures that there is no direct contact between metals, and make the operation more smoothly. It is the ideal option for adjusting the control or on/off control

9) Some specific model adopts a two-way adjustable stroke limit device

10) Long life lubricating grease of pneumatic cylinder actuator

11) ATEX certification II 2 G
