LHL Series Solenoid Valves

3-Port Latching - Plug-In: Conventional and Lo-Lohm Models

3-Port Plug-In Style Solenoid Valve

Optimized for applications that demand ultra-low power, low heat and small size, the 3-Port Latching HDI solenoid valve is ideal for compact, battery-operated portable instruments. This magnetically latched valve requires only momentary (10 to 30 ms) pulses to switch to and remain in each state, resulting in energy consumption of only 5.5 mJ per switch. The polarity of voltage on the terminal pins controls the switched position.

Standard part numbers for the Conventional and Lo-Lohm 3-Port Latching Plug-In style valves are listed below. The valves are offered in a variety of different flow rate ranges, seal materials and drive voltage configurations. The Lee Company also offers customized valve performance and manifold solutions to meet specific application requirements. Select the appropriate part number for your application in the table below, or contact your local Lee Sales Engineer for technical assistance.
