IEP Series 2-Way Dispense Solenoid Valve

This extended performance, high speed dispensing valve performs consistently under high pressure and high temperature conditions. Featuring a welded stainless steel construction with ports conveniently sized for all standard 1/16” ID ferruled compression fittings, this robust 6.5 mm axial flow valve offers rapid response times and can generate droplets at 500 Hz. Its high speed operation also enables accurate flow metering, acting as a replacement for some pressure regulators. Each valve is customizable and 100% tested to ensure performance.

*Some models are rated for 0 - 300 psig only. Reference part number table.
**Dispensing frequency is based on gas flow within the rated pressure range. Response times are impacted by various system parameters and are application dependent.
***A spike and hold drive is required for most applications. The minimum required spike (actuation voltage) is dependent upon pressure conditions.
****To ensure solenoid coil temperatures remain within specification, duty cycle limitations may be required. Reference part number table for max coil temperature recommendations. Contact The Lee Company for recommendations specific to your application.

*Actuate with rated spike voltage for 1 ms at 10 psig, 70°F (21°C). For higher pressure operation, a longer pulse duration may be required.
**Air at 70°F (21°C). Reference the flow curve under the product information tab for flow rate at varying pressures.
***FKM also available upon request.
****To avoid overheating and ensure solenoid coil temperatures remain within specification, it is not recommended to exceed 500 mW of average power. If active cooling is implemented, such as a fan or heat sink, a higher average power can be achieved. Contact The Lee Company for recommendations specific to your application.
