IEP Extended Performance Solenoid Valve - 1

PRODUCT DATA SHEET IEP EXTENDED PERFORMANCE SOLENOID VALVE The Lee Company’s IEP Series Extended Performance Solenoid Valve is designed to perform consistently under conditions that are far more demanding than typical high-speed dispensing applications. Available in a 2-way, normally closed, axial flow configuration, this compact solenoid valve expands on the operating pressure and temperature range capabilities of Lee’s micro-dispense valves without compromising reliability. Featuring welded stainless-steel construction and a wide selection of seal elastomers, this robust valve is suitable for flowing both gases and liquids in extreme environments. The valve design was optimized to achieve a perfect balance between switching and sealing performance making it ideal for a wide variety of applications such as CubeSat propulsion, precision combustion systems, gas chromatography, scanning electron microscopes, medical devices and other OEM applications. Performance parameters can be optimized to meet specific application requirements. Contact your Lee Sales Engineer for additional technical assistance and application information. ■ Compact size ■ Light weight: 4.7 grams ■ Low internal volume: 62 pL ■ Operating pressures up to 800 psig ■ ■ Operating temperatures up to 275°F (135°C) Flow capacity: 4100 Lohms (54 SLPM @ 800 psid, air; 70°F, Ref.

IEP Extended Performance Solenoid Valve - 2

LEE LOHM LAWS The Lohm Laws are a simple system of defining the fluid resistance of Lee components. Just as the "Ohm" is used in the electrical industry, we can use the "Liquid Ohm" or "Lohm" to quantify the resistance to flow of any fluid control component. When using the Lohm system, you can forget about coefficients of discharge and dimensional tolerances on drilled holes. These factors are automatically compensated for in the Lohm calculations, and confirmed by testing each component to establish flow tolerances. Gravimetric Flow Units LOHM LAWS (liquids) The Lohm has been selected so...
