Pneumatics Single Acting Standard Flow
Air Supply
Dry, oil-free, 5 micron filtered air (per ISA S7.3)
Action
Direct Acting
Supply Pressure
20-100 psi max. (1.4 to 6.9 bar)
Regulate 5 to 10 psi above actuator spring range. Do not
exceed actuator rating.
Air Delivery - Single Acting Relay
10.0 scf/min. (283 L/min) at 30 psi (2.1 bar) supply
16.6 scf/min. (470 L/min) at 60 psi (4.2 bar) supply
23.3 scf/min. (660 L/min) at 90 psi (6.3 bar) supply
Air Capacity
(flow coefficient)
Loading CV = 0.57
Venting CV = 0.53
Air Consumption
0.2 scf/min. (5.7 L/min) at 30 psi (2.1 bar) supply
0.26 scf/min. (7.4 L/min) at 45 psi (3.1 bar) supply
Air Supply Failure
Single Acting Relay
On supply failure the actuator output fails to atmosphere.
Some overshoot may occur when air pressure returns
after a period without air supply pressure. Always set con-
trol set point to 0%, and put the process control system in
manual, for smooth recovery from air supply failure.
Loss of Input Signal
Actuator Output fails to atmosphere
Output Pressure
0-150 psi (10.3 bar) max.
