D82 Handwheel Overtorque Protectors

Aunspach, overtorque protector, d82, Acrodyne, electric actuator, pneumatic actuator, handwheelManufacturer: Aunspach Controls Company

Model D82 Overtorque Protectors are mounted between the handwheel and electric or pneumatic actuator or as a shaft-to-shaft coupling. Operating torque is applied to the handwheel or driving shaft and transmitted thru the Model D82 to the driven equipment. The Model D82 will transmit operating torque only up to a pre-set amount.
If excessive torque is applied, the D82 drive will disengage and prevent equipment damage. Re-engagement is automatic and operation is the same in either direction of rotation.
