![Red-divider-solenoid Red-divider-solenoid](https://info.theleeco.com/hs-fs/hubfs/Red-divider-solenoid.png?width=150&height=20&name=Red-divider-solenoid.png)
Ideal for use in dialysis, apheresis systems, molecular diagnostics, respiratory therapy, environmental analyzers, breath analysis, patient simulators, and so much more.
NOT IN THE MEDICAL OR SCIENTIFIC FIELDS?
When there’s zero room for error, choose a valve that Hits the mark every time.
If you need a reliable, high-performance control solenoid valve, The Lee Company has your solution. We’ve been supplying space-saving fluid control components for medical and scientific applications for decades.
Our family of control solenoid valves includes 2- and 3-port miniature solenoid valves to control the flow of air, gases, or mild liquids. And if you’re looking for high flow, low power, latching designs, low leakage, compact size, or quiet operation, we have a valve that will suit your design criteria.

2-PORT & 3-PORT, 7 mm diameter
Conventional Solenoid Valves
LHD Series valves are compact, 7 mm control solenoid valves that offer superior performance across an extensive cycle life. With a flow capability of 450 Lohms (18 LPM minimum at 15 psig), power as low as 310 mW, and leakage less than 50 µLPM, these valves maximize performance without compromising reliability.

2-PORT & 3-PORT, 7 mm diameter
latching Solenoid Valves
LHL Series valves are compact, 7 mm magnetically latched control solenoid valves that feature ultra-low power consumption (as low as 5.5 mJ/switch) and low heat dissipation. Ideal for battery-powered instruments flowing air or gas, these valves require only momentary pulses (10-30 ms) of current to switch to and remain in each flow state. While being held in a specific flow state for an extended period of time, these valves don’t consume power, generate heat, or produce electrical noise. In addition, LHL Series valves provide reliable bi-stable switching performance in the smallest footprint possible.

3-PORT, 7 mm diameter
Quiet Operation Solenoid Valves
LHQ Series valves are compact, 7 mm quiet operation control solenoid valves that feature whisper technology to reduce actuation noise. When a typical solenoid valve is energized, there is an inherent clicking sound caused by the metal-to-metal contact of the moving armature and stationary core. With a low sound profile that is 50% quieter (≤ 30 dBA) than our already best-in-class LHD Series solenoid valve, this reliable design is ideal for bedside applications flowing air or gas.
