LHD Series 3-Way Control Solenoid Valve

This small (7 mm), 3/2, direct-acting valve is used to control the flow of gases and mild liquids. The valve’s low power, low leakage, and long cycle life offer high value at an economical price in many applications, including microfluidic piloting and directional flow control to sensors. Just plug one port and the valve will also act as 2-way normally open or closed valve. Available in a wide range of models, this valve can be connected to your system using tubing or manifold mounted with ease in a tight space. Each valve is customizable and 100% tested to ensure performance.

Face Mount Configuration. With the fluidic ports surface mounted via a one-piece gasket, the face mount style lends itself easily to machined or molded manifolds, enabling multiple valves to be mounted in an incredibly small package. Plug one port and the valve will also act as 2-way normally open or closed valve.

Unless otherwise indicated, listed specifications are on air at 70°F (21°C).
1A spike and hold electrical drive is required for most applications. To ensure solenoid coil temperatures remain within specification, duty cycle limitations may be required. Contact The Lee Company for recommendations specific to your application.
2Our standard 3-way valves are available in two porting configurations: (1) common inlet - the highest absolute pressure, often the inlet pressure, must be maintained at the common port; (2) any port inlet - the highest absolute pressure can be connected to any port. Bidirectional valves are also available upon request.
3Reference the flow curve under the product information tab for flow rate at varying pressures.
4Maximum differential pressure across valve ports. Models rated for 30 psid up to 100 psid are also available upon request.

1Several standard manifolds are available to ease prototype setup. They are available in mounting denominations of single valve (1x), three valves (3x) and eight valves (8x). Combine these denominations or plug unused ports to configure the setup for your specific application. Manifold part numbers include the manifold and secondary retention bracket only. All solenoid valves are sold separately. Alternate materials and customized manifold designs are available upon request.
2For use only with valves rated to 1100 Lohms or higher.
