Certain Change-over Valves are equipped with a flushing and pressure gauge
connection. The flushing and pressure gauge connection is designed for the
attachment of a check gauge. The check gauge is used to check whether there
is any pressure left in the blocked elbow before the safety valve is removed.
After removal of the safety valve, the depressurised elbow of the Change-over
Valve can be flushed through the flushing and pressure gauge connection.
