Does your application require the valve to move to it´s safety position by itself e.g. if the actuator’s cable is destroyed, or your plant experiences a power failure in certain areas? A so called “fail-safe” function is then necessary and  TA Roloff has the most advanced solutions. Proceed to our website and click on the “Fail-safe” button to learn more about the selection and  functionality of various fail-safe options.
