Abstract
A valve arrangement of an irrigation system includes a by-pass; for controlling the return flow of a pilot valve, which by being connected between the outlet connection from the pilot valve and the return connection to the pilot valve eliminates the need for a return circuit and enables the arrangement to be connected downstream to an open circuit network used for the pulsating delivery of an irrigation liquid.
