Solenoid Valves

Hypodermic Port Outlet VHS® Series Solenoid Valve

This 6 mm, 2-way (2/2) dispensing solenoid valve has an integrated hypodermic outlet port nozzle that enables dispensing of droplets as small as 20 nanoliters, and practical time-metered dispensing up to 1 ml. With the addition of a mounting sleeve, the valve can also be manifold mounted which enables the precise injection of fluids directly into flow streams. Available in two inlet port options, these valves are ideal for numerous precision dispensing applications in diagnostics and biotech, including lateral flow strip manufacturing, well plate dispensing, and bioprinting, and for dispensing coatings and sealants in industries such as semiconductor manufacturing. Each valve is customizable and 100% tested to ensure performance.

1Refer to our MINSTAC offerings for compatible tubing assemblies, threaded safety screens and more.
2Some models are rated for 0 - 30 psig only. Reference part number table.
3Typical cycle life on water; actual cycle life will vary depending on application conditions.
4Valve is sensitive to particles that are hard and fibrous. Larger, flexible particles, such as cells, can be qualified for applications.
5Dispensing frequency is based on water flow within the rated pressure range. Response time and dispense volume profile are drive dependent and vary depending on system parameters.
6A spike and hold 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.

Get Started

Are you ready to get started? We offer a VHS Valve Evaluation Kit (part number IKTX0322000A) for easy setup and development testing of a dispense system. All that is required is a pressurized fluid source, control signal, and a power supply.

One MINSTAC INLET/MINSTAC OUTLET VHS Series solenoid valve (24VDC, EPDM) is included, along with a spike and hold driver, nozzles, and numerous accessories. This M/M configuration allows you to quickly iterate your dispense setup with the use of various threaded 062 MINSTAC nozzles. If you’d like to test a different outlet configuration, those valves can be purchased separately from the kit and must be rated for a 24 VDC spike voltage.
