What we Do
We manufacture high-performance, predictable and reliable POSITIVE-ACTION OVERTORQUE RELEASE CLUTCHES , and specialize in serving the valve, gearbox, actuator and machinery markets - offering the highest quality products and support. We offer turn-key solutions for new and retrofit applications.
Our Technology
Our OVERTORQUE CLUTCHES are mechanical torque limiters that will only allow the proper (SAFE) amount of input torque to pass into valves/actuators/gearboxes or machinery.
Any torque that exceeds the set-point is not passed through into the equipment. If input torque exceeds the OVERTORQUE CLUTCH set-point, it completely DISCONNECTS from the equipment (temporarily), preventing excessive torque from transferring into the equipment. Reconnection happens automatically, without user intervention. Only the proper (SAFE) amount of torque is applied.
Our products utilize proprietary spring & ball/roller-detent technology to provide durable, precise and repeatable overtorque protection, with superior performance and dependability compared to friction clutches and other methods. Our sealed products exceed IP68 water ingress rating and are fully-submersible. ZERO maintenance is required.
