LHL Series Solenoid Valves

2-Port Latching - Plug-In: Conventional Models

2-Port Plug-In Style Solenoid Valve

Optimized for applications that demand extremely low power, low heat and small size, the 2-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. The polarity of voltage on the terminal pins controls the switched position. With energy consumption as low as 10 mJ/switch, this small solenoid valve’s wide range of performance capabilities will surpass your expectations for a product of its size.

Standard part numbers for the Conventional 2-Port Latching Plug-In style valves are listed below. The valves are offered in a variety of different 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.
