Declutchable Manual Override for Series 79 Actuator

The declutchable manual override for the series 79P is a gear box for manually operating the 79 series pneumatic actuator from Asahi/America. The gear box itself mounts between the pneumatic actuator and valve. The featured declutch mechanism is used for separating the actuator drive from the valve and allowing for operation via the attached handwheel. Made to fit sizes B79 through M79 and can be used with both air to air and air to spring type actuators. Gear box sizes vary with the actuator size to allow for manageable operating torques.
