Control solenoid Valves for Medical and Scientific Applications
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.
For reliable, high-performance control solenoid valves, The Lee Company delivers proven solutions engineered for demanding applications. For decades, we’ve specialized exclusively in space-saving, precision fluid control components for medical and scientific devices where performance, consistency, and reliability cannot be compromised.
Our family of 2- and 3-port miniature control solenoid valves offers high flow in compact packages, low power and latching options, ultra-low leakage, and quiet operation—giving you design flexibility without tradeoffs.
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. Designed for demanding applications, they provide an optimal balance of flow, power efficiency, and leak integrity.
Key Features:
- High Flow Capability: 450 Lohms (18 LPM minimum at 15 psig)
- Low Power Consumption: as low as 310 mW
- Ultra-low Leakage: less than 50 µLPM
- Compact & Lightweight: 7 mm & 2.5 grams
2-PORT & 3-PORT, 7 mm diameter
latching Solenoid Valves
LHL Series valves are compact, 7 mm magnetically latched control solenoid valves designed for ultra-low power consumption and minimal heat dissipation. They are ideal for battery-powered instruments flowing air or gas where extremely reliable performance and low leakage are critical.
Key Features:
- Latching Design: Holds latched state without power
- Ultra-low Power & Low heat: as low as 5.5 mJ/switch
- Momentary Actuation: 10–30 ms current pulses to change states
- Bi-stable switching: reliable magnetic latching in each flow state
- Compact & Lightweight: 7 mm & 4.5 grams
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. Designed to minimize actuation noise caused by metal-to-metal contact, they are well suited for noise-sensitive environments.
Key Features:
- Quiet actuation: up to 50% quieter than LHD Series (≤ 30 dBA)
- Whisper technology: reduces actuation noise when solenoid valves are engergized
- Compact & lightweight: 7 mm & 4.5 grams
- Reliable performance: 25 million cycles minimum
- Ideal applications: patient simulators and a variety of bedside pneumatic applications
