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.
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. Testing capabilities include the following: This product may be covered under one or more of the following patents: Please be sure to include the model number if you have it.

Step siw test — Test evaluates hysteresis, dead time, overshoot and stroking time. Dimensions for valve-mounted instruments are shown in figures 1, 2, and 3.
Partial stroke testing — Test verifies valve movement, without fully stroking the valve. Refer to the appropriate product bulletin, listed in Related Documents, for additional information about these digital valve controllers. Valve signature test — Test benchmarks valve operation by determining spring rate, seating forces, friction and bench set. As with most industrial process operations, the safety risk to personnel, equipment and the environment in case of an emergency is ever-present.
