Description
1/8"–1/2" Brass Latching Solenoid Valve 12VDC or 24VDC – CS Fluid Power LAD612 Series
A compact, direct-acting 2/2 way latching (bi-stable) brass solenoid valve designed for air, water, light oils and vacuum applications where ultra-low power consumption is required. The LAD612 Series uses a magnetic latching mechanism that requires power only during switching, making it ideal for battery-powered equipment, remote installations, energy-saving systems and portable control equipment.

How Latching Operation Works
The LAD612 Series requires only a brief electrical pulse to change valve position.
A pulse with the correct polarity energises the internal magnetic actuator and opens the valve.
Once open, the valve remains open without consuming electrical power.
A reverse polarity pulse de-energises the internal magnet, causing the valve to close and remain closed without power.
To reopen the valve, simply reverse the polarity back to the original configuration and apply another pulse.
This latching technology dramatically reduces power consumption and heat generation compared with conventional continuously energised solenoid valves.
