US Patent Issued to Watts Regulator on Sept. 8 for "Torque limiter coupling assembly for valve actuators" (German Inventor)

ALEXANDRIA, Va., Sept. 8 -- United States Patent no. 12,729,776, issued on Sept. 8, was assigned to Watts Regulator Co. (North Andover, Mass.).

"Torque limiter coupling assembly for valve actuators" was invented by Markus Kroll (Dattenberg, Germany).

According to the abstract* released by the U.S. Patent & Trademark Office: "A torque limiting coupling assembly shields a valve actuator from abnormally high levels of torque. In normal operation, an actuator coupling transfers a driving torque from an actuator coupling to a valve shaft coupling and the valve shaft coupling engenders a shaft torque on a shaft of a valve. In torque actuated operation, when a counter torque applied to the shaft coupling exceeds a threshold value, the actuator c...
