Control Valve Fail Close at Angus Daplyn blog

Control Valve Fail Close. If the process is safer using a “fail open” valve, we need to select the air to close (fo) control valve. The valve continuously monitors itself for the power supply or pressure handling. If the valve fails closed, the engine will surely overheat from lack of cooling. If it fails open, the engine will merely run cooler than designed, the only negative consequence being decreased. So in the select control valve failure mode, we need to combine the basis of all instrumentation actions in the critical control loop, then determine the safest failure mode for the process. Fail open valves — also known as spring to open or air to close valves — are commonly used to prevent a buildup of excessive pressure within a piping system when the power or signal is lost. For instance, they are used in fuel supply systems for. Fail closed (fc) means that when the signal is lost, the valve closes. Fail close valves (fc), also known as normally closed (nc) valves, are designed to automatically return to a closed position in the absence of power or when a failure occurs within the system.
