SD10 Valve Overtorque Protectors
Operating torque is applied through a handwheel or other means and transmitted through the Model SD10’s shaft to the detent plate, drive balls, body, and then to the driven equipment. If excessive torque is applied, the drive balls will rise out of the detents against the force of the springs and disengage the drive. Re-engagement at the pre-set trip torque is automatic, with further rotation in either direction.
The purpose of the Model SD10 Overtorque Protector is to prevent valve, actuator and/or other equipment damage by limiting the amount of operating torque that can be applied.
