A double block and bleed valve is often used for a more positive isolation of a process fluid from other equipment. It normally consists of 2 block valves and a bleed valve, which apart from being hugely space saving can also save on time during installation and maintenance process. When the process fluid is feeding the downstream equipment, the isolation valves 1 & 2 are opened and bleed valve 3 is closed.When the downstream equipment is to be isolated from the process fluid, the isolation valves 1 & 2 are closed and bleed valve 3 is opened.This is achieved by two Ball, Gate, Globe, Needle, etc valves placed back to back with a third "isolate" valve in the centre cavity. Uses: In some automatic shutdown systems, to stop material flow, such as in fuel gas system for burners. to provide isolation of hazardous material, temperature or pressure during equipment maintenance or shutdown process.

The dual flow shutoff valve (DFSOV) controls the nitrogen enriched air (NEA) flow to the fuel tanks of an aircraft as part of an inert gas generation system. The DFSOV is used for switching the NEA flow between off, low, medium and high flow. Its secondary but critical function is to prevent fuel and fuel vapor migration from the fuel tank back to the ASM when the system is not operating.
