Operation
Closed condition:
In the closed position, the control valve shuts off the connection between the vacuum piping and the discharge valve
housing. As the valve housing then is under atmospheric pressure, the spring-loaded closing mechanism closes the
rubber diaphragm and isolates the bowl from the vacuum piping.
Flushing condition:
As the control valve opens, the discharge valve housing is subjected to vacuum, thus forcing the closing mechanism
to open. This in turn allows the rubber diaphragm to open, and connects the bowl to the vacuum pipe line.
Maintenance
See document 3:01054C for scheduled maintenance.
