Table 15 High Flow Pneumatics Single Acting High Flow
Air Supply Dry, oil-free, 5 micron filtered air (See ISA S7.3)
Action Direct Acting
Supply Pressure 20 -100 psi max. (1.4 - 6.9 bar)
Regulate 5 - 10 psi (.345 bar - .69 bar) above actuator
spring range. Do not exceed actuator rating.
Air Delivery - Single Acting Relay 39.0 scfm (1104 l/m) at 30 psi (2.1 bar) supply
70.6 scfm (2000 l/m) at 60 psi (4.2 bar) supply
102.0 scfm (2888 l/m) at 90 psi (6.3 bar) supply
Air Capacity
(flow coefficient) Loading CV = 2.2
Venting CV = 2.2
Air Consumption 0.28 scfm (8.0 sl/m) at 30 psi (2.1 bar) supply
0.35 scfm (10.5 sl/m) at 45 psi (3.1bar) supply
Air Supply Failure Single Acting Relay
On supply failure the actuator output drops. Some
overshoot may occur when air pressure returns after a
period without air supply pressure. Always set control
set point to 0%, and put the process control system in
manual, for smooth recovery from air supply failure.
Loss of Input Signal Output drops to low pressure.
Output Pressure 0-150 psi (10 bar) max
