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 5ºCshall 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 betop 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 1-8Pneumatic parallel double disc gate valve
