Fail Lock Open Valve. control valve failure mode. fail close valves close in the event of a failure or power loss, while fail open valves open. In order for a pneumatic or hydraulic valve to fail in the locked state, an external device must trap. Fail close valves are often used in critical applications where a flow loss could be dangerous. On the other hand, fail open valves are often used in applications where a loss of flow is not critical. it depends on the valve. fail open (fo) means that when there is a loss of signal, the valve opens. “fail open(fo)” means air to close, and the control valve is normally at an open position, only when lost air supply,. 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. fail close valves (fc), also known as normally closed (nc) valves, are designed to automatically return to a closed position.
