Solenoid valves are electrically controlled, hydraulically operated valves. There are lots of options available including normally closed (most common - valve opens when power applied), normally open (valve closes when power applied), pressure reducing. Valves also come with many different electrical options including 24vAC (most common for irrigation systems), 12vDC and 12vDC Latching (used on some battery powered irrigation systems). Our High Flow range include many more electric and flow control options and come in sizes up to 150mm.
Unless otherwise stated these valves require a minimum of 7m head pressure to operate correctly and may not be suitable for some low pressure or gravity fed systems.
