Isolation Valve Closing

‘An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes. This valve can be used to isolate a process from another process or section of the same process. An Explosion Isolation Valve (EIV) prevents the spread of flames and pressure (in both upstream and downstream directions), effectively preventing an explosion from propagating through your process piping or duct work.’

‘Isolation valves are a key component in any fluid system as they are used to stop the flow of fluid into a particular part of the system. They are also sometimes used to manually control the flow of the fluid. An Isolation Valve is a valve intended for use only in the closed or fully open position. Isolation valves are used in a wide variety of different applications where on/off type control is required, these include: diverting process media; flow isolation to facilitate maintenance, allowing the removal of equipment and allowing the shutdown of plant.’
