Meet the EFS Family
A family that works together as a complete unit can achieve extraordinary things. Our integrated family of miniature, precision, solenoid valves, dispense pumps and inert fluid handling components has been helping designers move beyond the ordinary for over 60 years. How? Superior reliability, consistent performance, and top-notch technical support, including custom design capability. If you’re designing a fluid handling system, nobody makes precision fluid control products better and in a wider selection than The Lee Company. Put our family’s experience to work for you, and make your next design extraordinary.
Micro-Dispensing and Drop on Demand components include high speed dispensing valves and nozzles for use with inks, air, biological reagents and a wide range of other fluids.

Control Valves feature small size, precision performance and long life often exceeding 200 million cycles. These valves are often supplied on manifolds and/or customized to meet special OEM requirements.

 
Our Scientific Products, including Inert Valves and Pumps are often used in medical and scientific instrumentation where reagents and fluid samples must be handled without contamination. These are often supplied on manifolds and/or customized to meet special OEM requirements.
