899 results about "Isolation valve" patented technology

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. They can also be used to provide flow logic (selecting one flow path versus another), and to connect external equipment to a system. A valve is classified as an isolation valve because of its intended function in a system, not because of the architecture of the valve itself. Therefore, many different types of valves can be classified as isolation valves.
