Introduction of operating conditions for pneumatic actuators

The operating conditions of pneumatic actuators are introduced.
1. The working environment temperature of pneumatic actuator:
1, the standard type is -20 C to +80 C;
2, the low temperature type is -40 C to +80 C;
3. The high temperature type is -20 C to +160 C.
Two. The pressure of origin:
3bar to 8bar.
Three. The operating medium of pneumatic actuator:
1. The dew point temperature of the operation medium of the pneumatic actuator is -20 degrees, and the impurity particle size in the medium does not exceed 30 mu.
2. Clean, dry or lubricated air or inert gas, as long as non corrosive gases compatible with internal parts and lubricants of the actuator.
3. When selecting positioners, the size of the impurity particles in the medium should not exceed 5.
