Normally Open ("NO") valves are the better choice where water flow needs to be stopped only under certain conditions — the opposite of Normally Closed ("NC") valves, which consume power continuously to stay open and only need power to shut. Because NO valves are made from tough engineering plastics, they offer long service life at a lower cost than equivalent metallic valves, with equal or better performance and a compact internal-pilot package.

Available in a range of coil voltages; custom-designed valves and voltages can be supplied against specific order.
