Supply Pressure
(1)
Minimum Recommended: 0.3 bar (5 psig) higher
than maximum actuator requirements
Maximum: 10.0 bar (145 psig) or maximum pressure
rating of the actuator, whichever is lower
Supply Medium
Air or Natural Gas
Air: Supply pressure must be clean, dry air that meets
the requirements of ISA Standard 7.0.01.
Natural Gas: Natural Gas must be clean, dry, oil‐free,
and noncorrosive. H
2
S content should not exceed 20
ppm.
Filtering and Air Handling
A maximum 40 micrometer particle size in the air
system is acceptable. Further filtration down to 5
micrometer particle size is recommended. Lubricant
content is not to exceed 1 ppm weight (w/w) or
volume (v/v) basis. Condensation in the air supply
should be minimized.
Per ISO 8573-1
Maximum particle density size: Class 7
Oil content: Class 3
Pressure Dew Point: Class 3 or at least 10 K less than
the lowest ambient temperature expected
Output Signal
Pneumatic signal, up to full supply pressure
Minimum Span: 0.4 bar (6 psig)
Maximum Span: 9.5 bar (140 psig)
Action:
