Change-over valves are used to connect two safety valves to a pressure system using one joint pipe. The operating system runs normally, with one safety valve in operation while the other is on stand-by. This allows the stand-by valve to be removed and even serviced during ongoing operation.
Change-over valves are used in processes in which shutting down the plant is not possible or not desired because continuous operation is required.
AZ-Armaturen supplies different types of cross-over valves – depending on the technical requirements, which provide a safe, reliable and long lasting solution for the change over between safety valves.
