This 6 mm, 2-way (2/2) dispensing solenoid valve achieves accurate fluid regulation and dispenses precision droplets in the nanoliter to milliliter range when connected to a downstream nozzle. The molded outlet port is designed for connection to 1/32″ ID flexible tubing and a precision nozzle downstream. This permits nozzles to be placed closer than valve center to center distance allows, enabling the valve to be located remotely and saving space at the dispense head. Compatible straight tube nozzles are available and can be pushed directly into tubing, enabling rapid iterative testing of various jeweled orifices. 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 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.

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.
These Application Notes provide practical guidance on how our disc pumps can be used across a variety of applications.

FLUIDIC CONNECTIONS & ACCESSORIES
Our Miniature Inert System of Tubing and Components (MINSTAC) product line offers numerous options for fluidic connection to the VHS Series valves. This includes tubing assemblies optimized for low shear, and low internal volume, as well as inert check valves, safety screens, filters, adapters and unions. Recommended part numbers that enable connection to the barbed or threaded 062 MINSTAC inlet ports are included in the tables below.
NOZZLES
Several dispense nozzles are also listed in the table below. These enable quick and easy testing of various orifice sizes, With jeweled orifices as small as 0.002 of an inch (0.05 mm), these interchangeable straight tube dispense nozzles are capable of dispensing droplets as small as 10 nanoliters and larger volumes depending on the time-metered dosing setup and valve cycle times. Intended to be pushed into soft tubing, they are compatible with the molded port outlet versions of the VHS Series valve (configurations P/P and M/P). Wetted materials are simply stainless steel and sapphire.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
