LFA Series Solenoid Valves

Miniature Piloting Solenoid Valve

The Lee Interface Fluidic (LFA Series) Solenoid Valves offer small size and light weight, without sacrificing performance. Designed for applications where space is limited, these valves are generally used for medical and scientific applications flowing air or gas, such as blood chemistry instruments, ventilators/respirators, gas analysis equipment, blood pressure monitors and various other flow switching devices.

LFA Series valves are available as a 2-way (normally closed) or 3-way soft tube ported design with two electrical connection options; printed circuit board mount or lead-wires. The following general performance characteristics are offered in this product platform:

  • Operating Pressures up to 30 psig
  • Power Consumption as Low as 280 mW
  • Response Times as Fast as 1.5 ms
  • Low Internal Volume
  • Standard Voltages Available: 5, 9, 12, 24 vdc
  • Several Lohm Rates: 1000 to 1800

Each valve is 100% functionally tested for switching voltage, flow capacity, and leakage. Rugged materials are used to ensure consistent long-term performance. The valves will typically operate up to 200 million cycles on air, depending on the seal material and application parameters.
