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.

Fisher FIELDVUE DVC6000 SIS Digital Valve Controller
Instrumented protection systems, such as Safety Instrumented Systems SISare engineered to monitor for potentially hazardous conditions and, ideally, limit the damaging effects of an emergency event. Ready for a quote? Partial stroke testing — Test verifies valve movement, without fully stroking the valve.
As with most industrial process operations, the safety risk to personnel, equipment and the environment in case of xis emergency is ever-present. Responsibility for the selection, use, and maintenance of any product remains with the purchaser and end-user.
Step response test — Test evaluates hysteresis, dead time, overshoot and stroking time. Dimensions for remote mounted instruments are shown in figures 4, 5, 6, 7, and 8. This dangerously prevents the SIS from performing the way it is designed.

To achieve this, the SIS triggers a valve to adjust the process to a safe state. Valve signature test — Test benchmarks valve operation by determining spring rate, seating forces, friction and bench set.
Refer to the appropriate product bulletin, listed in Related Documents, for additional information about these digital valve controllers. Procedural testing of these valves is historically accomplished by way of a pneumatic test panel near the valve, which is often a clunky and laborious process and can result in needing to lock the valve in position or bypass it completely.
Gathers diagnostic data and sends out an alert in the event the valve is struck. Remote venting is available.
Electrical connections are made in the terminal box. Please leave this field empty. Neither Emerson, Emerson Process Management, nor any of their affiliated entities assumes responsibility for the selection, use or maintenance of any product.
