Magnetic Latching Valves

Magnetic Latching Valves
Through the use of a permanent magnet, the latching valves are bi-stable in either shifted state. This allows the valve to stay in either state indefinitely without drawing power. To shift the valve from one state to another, a short 50 millisecond DC voltage is applied to the coil. To shift the valve back, a reverse polarity pulse is applied to the coil. This feature makes this valve suitable for use in remote areas where continuous power may be limited. It is also valuable in equipment where coil heating, due to a continuous application of power, is undesirable such as in medical and chemical analyzers.

 

2-Way Normally Open Magnetic Latching Valves

PeterPaul single orifice valves in which the orifice is closed in the energized position and no flow can exist between the inlet and outlet ports.
