0.529 scf/min. (15 sL/min.) at 120 psi (8.28 bar, 828 kPa) supply
Single Acting Relay
On supply failure the actuator output drops. Some overshoot can occur when air
pressure returns after a period without air supply pressure. Always set control set
point to 0%, and put process control system in manual, for smooth recovery from
air supply failure.
Output drops to low pressure.
