valves; the primary function of the DVC SIS digital valve controller is to This guide describes how to install, setup, and calibrate DVC SIS digital. FIELDVUE DVC SIS digital valve controllers. (see figure 1). Using the DVC SIS permits partial stroking of the valve to reduce the Probability of Failure. Separation of the Fisher® FIELDVUE™ DVC’s travel sensing and controlling segments helps meet extreme temperature and vibration.
