Solenoid Valves

Integrated Orifice Outlet VHS® Series Solenoid Valve

This 6 mm, 2-way (2/2) solenoid valve has an integrated sapphire orifice that enables droplet dispensing in the 10 nanoliter to microliter range directly from the valve itself (no need for an additional nozzle). This outlet type is available in two different styles: the simple IO-style is easiest to flush, while the long-throw-style (LT) incorporates an internal pressure compensation bladder, allowing the droplet to retain its integrity longer and travel farther. Available with 062 MINSTAC or barbed inlets, three seal material options, and multiple orifice sizes, 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.

1A spike and hold electrical 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.
2 Lohm rating of each valve model is based on air performance. Reference the flow curve under the product information tab for typical flow characteristics on water.
3Integrated Orifice (IO) Outlet valves are available with either a 0.003”, a 0.005” or a 0.007” precision orifice integrated into the valve’s outlet. Each is also available in two different styles. The simple IO style is easiest to flush, while the Long Throw (LT) style incorporates an internal pressure compensation bladder. This bladder allows the droplet to retain its integrity longer, enabling it to travel farther.

Installation & Accessories

FLUIDIC CONNECTIONS, NOZZLES, & ACCESSORIES
