This invention relates to a device and method for converting low continuous flow to a high intermittent and pulsating flow arid is especially adapted for operating sprinklers, showerheads etc. at low flow. Fluid is introduced at a controlled low flow, such as by the use of a dripper (5, 24) in a supply line (7), into a container (1, 22) having expandable chamber (2). The outflow of li- quid from the chamber (2) is restricted until pressure created by the introduction of the liquid is sufficient to force the valve to open, and in response to a resistance to the flow, the fluid intermittently ejects at a higher flow. This is achieved by utilizing a preset pressure responsive valve (8, 28), designed for quick response, to create a water hammer effect. The invention describes pulsating valves and other devices operating in response to deformation created in elastic membranes in response to pressure changes.
