Acrodyne introduces the Acro-Gears Aunspach Torque Master Handwheel Overtorque Protector, was developed after observing that many valves and actuators are damaged each year by excess operating torque. The company says a one-time “Insurance Premium” of an amount typically less than 1% of the installed valve/actuator value will prevent over-torque damage for the life of the valve/actuator. The protectors are typically mounted between the handwheel of a manual actuator or on the manual override of an electric or pneumatic actuator. These will transmit operating torque but, if a pre-set torque is exceeded, will declutch and prevent damage. The drive will re-engage automatically, at the original set point, upon further rotation in either direction.
