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. Electrical connections are made in the terminal box.

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. Dimensions for remote mounted instruments are shown in figures 4, 5, 6, 7, and 8. All sales are governed by our terms and conditions, which are available upon request. All other marks are the property of their respective owners. This dangerously prevents the SIS from performing the way it is designed.

Step response test — Test evaluates hysteresis, dead time, overshoot and stroking time. Ready for a quote? Dimensions for valve-mounted instruments are shown in figures 1, 2, and 3. As with most industrial process operations, the safety risk to personnel, equipment and the environment in case of an emergency is ever-present.
