Beschreibung
Zusammenfassung:	An irrigation valve comprising: a solenoid valve (120, 20, 300), the solenoid valve (120, 20, 300) comprising; a solenoid configured to actuate a plunger (316) to open or close the solenoid valve (120, 20, 300); at least one pressure sensor (150, 318, 320, 380) configured to measure inlet fluid pressure and/or outlet fluid pressure of the irrigation valve; and a control unit (135, 380) configured to generate a control signal in response to a measured pressure reading from the at least one pressure sensor (150, 318, 320, 380); wherein the at least one pressure sensor (150, 318, 320, 380) is configured to measure the valve outlet pressure when the plunger (316) is in a first position; and wherein the at least one pressure sensor (150, 318, 320, 380) is configured to measure the inlet fluid pressure when the plunger (316) is in a second position. A related irrigation system and methods of monitoring fluid flow through an irrigation valve and of controlling fluid flow through such an irrigation valve are also disclosed.
