Types of flush rings

A flush ring according to the chemical group’s specifications. It is mounted with a flange connection located between the primary isolation valve and the diaphragm seal. One or two ventilation and flushing connections are located on the outside of the flush ring. If the ring only has one connection, the cavity between diaphragm seal and primary isolation valve can be flushed in a controlled manner - for example, via a connected hose and a suitable collection container. The ring can, for example, be filled with compressed air or a cleaning fluid via the second connection and flushed out depending on requirements which the corresponding medium places on the system operator.
