Note 6) Values at the standard supply pressure. Values are based on standard of SMC measurements. They depend on
atmospheric pressure (weather, altitude, etc.) and measurement method.
Note 7) The value in ( ) is for without valve.
Note 8) The value in ( ) is for without valve. For nozzle size 07 to 12, the value is common to the ejectors with valve and without
valve.
