Valve Failure Position at Carl Eason blog

Valve Failure Position. it depends on the valve. It is important to remember that valves are generally pneumatic, meaning that their function is based off of air pressure. in the previous section, some of the most common control valve failure modes (mechanisms) were described. an important design parameter for control valves is the position to which the valve will fail if power or signal is lost. Mapping these to an fmea we need to: Each having its own consequences and safety effects. first determine the safest mode of valve failure, then select and/or configure instrument actions in such a way that the most probable modes of signal path failure will result in the control valve consistently moving to that (safest) position. There are a few different fail scenarios; On a kimray high pressure control valve, there is a position indicator attached to the stem that shows if the valve is open or closed. this situation is known as the valve’s failure mode—the position the valve assumes when there is a loss of signal or power. the valve’s fail position is a safety precaution that protects your process in emergency situations.
