Description
Single-acting, spring-return pneumatic actuator for automating quarter-turn ball valves, butterfly valves and dampers. Supply air drives the valve to one position and the springs return it to the safe position when air or the pilot signal is lost, which is the usual choice for emergency shut-off on fuel, gas, water and steam utility lines.
Fail-closed (SR-FC): springs close the valve on loss of air. Fail-open (SR-FO): springs open the valve on loss of air. Control it with a 3/2 or NAMUR solenoid valve; for double-acting units see our AT32–AT92 actuator.
