Baffle plate

The outflow valve and diaphragm section con­tains a base, a spring-loaded outflow valve, an actuator diaphragm, a balance diaphragm, and a baffle plate. The baffle plate is attached to the end of a pilot which extends from the centre of the cover assembly. The outflow valve rides on the pilot between the cover and the baffle plate and is spring loaded to a closed position against the base.
