A valve controls the rate of flow of fluid through its outlet pasage by selective alignment with the passage of a jet having an orifice of area less than that of the outlet passage. A plurality of jets in a single valve provides variable flow rate control and interchangeability of jets allows use of the same valve in a wide variety of applications and environs. The same valve can further be easily adapted for continuous or intermittant flow operation.
