Pneumatic actuator performance parameters

1. Design pressure: 1.0MPa

2. Working pressure: 0.35~0.7MPa

3. Working medium: purified compressed air

4. Applicable environmental temperature: standard type (-20~+70ºC), low temperature type (-40~+70ºC)

5. Medium temperature: 5~55ºC (Compressed air lower than 5ºC shall be subject to special dewatering treatment.)

6. Form and action:

 Single acting piston type (spring return), acting type: F.C or F.O

 Double acting piston type, acting type: F.L

 Double acting piston type with accident air tank, acting type: F.C or F.O

7. Handwheel mechanism form:

 Handwheel: According to the installation positions, it can be  top handwheel,  top side-mounted handwheel,  Middle side-mounted handwheel (See figure 2.1~2.8.)

 Hydraulic hand-operated mechanism: only used for single acting (spring return) actuator with relatively high output force and travel (See figure 2.9~2.10.)

8. Pneumatic shut-off full-travel time: see table 1-8
