Description
3/8"–1½" Latching Plastic Delrin Solenoid Valve 0.5–10 Bar – CS Fluid Power LPA Series
A corrosion-resistant, pressure-assisted 2/2 way latching (bi-stable) solenoid valve manufactured from POM (Delrin®) and designed for pure water, RO water, demineralised water and other compatible fluids and gases. The LPA Series uses a magnetic latching mechanism that requires power only during switching, making it ideal for battery-powered equipment, water conservation systems, remote installations and energy-saving applications.

How Latching Operation Works
The LPA Series requires only a brief power pulse to change valve position.
A pulse of the correct polarity energises the internal magnet and changes the valve state.
A reverse polarity pulse de-magnetises the actuator and returns the valve to its previous position.
Once switched, the valve remains in its current position without consuming any electrical power.
This makes the LPA Series ideal for battery-powered, solar-powered and energy-efficient systems.
