Solenoid Solutions presents new magnetic latching valves that require no energy to “remain” open. These valves use a permanent magnet built into the valve to hold the plunger in the open position; thus, they do not require continuous power to keep the valve open or operating.
A 2-way, normally closed latching valve requires only a burst of energy to lift the plunger into the open position, and then it is held in place by the permanent magnet. The valve is powered off and remains open until another electrical charge of opposite polarity, is applied.
This is ideal for applications where the valve remains open for long periods or if the valve is battery powered and must conserve as much energy as possible.
