Lee Bender Jet Multi-Orifice Restrictors

The Lee Visco Jet® is one of our most unique innovations. It creates a highly complex fluid passage with a series of individual spin chambers and orifices. This provides an increase in flow passage as great as 25 times that of a corresponding (same Lohm rate) single-stage restrictor, with a corresponding reduction in velocity.

Visco technology offers multiple benefits, including increased resistance to contamination and reduced erosion. Its design prevents cavitation and creates a degree of viscosity compensation. To learn more about how Lee Visco Jet technology works, watch this short video.

Visco Jets are available in flow rates up to 313,000 Lohms in a 0.187 inch diameter cartridge and up to 2.2 million Lohms in a 0.43-inch diameter cartridge. There is no other product available that can provide this level of restriction with such a large minimum passage in such a tiny package.

This is our standard non-biased loose-ball design. Available in 0.187, 0.281, 0.375, and 0.500 inch diameters, these are the most economical configuration. The maximum shuttling pressure is just 1 psid. The valves are rated for leakage of fewer than 1 mL per minute.

Lee 187 Insert Retained Drilled Safety Screens combine a Lee locking end with a robust, one-piece screen element. Using the proven Lee Insert Principal (refer to our website, or the Lee Technical Hydraulic Handbook for additional details), these screens allow for a simple installation directly into a fluid passageway. This installation technique locks the screen into the surrounding housing and provides a reliable, leak-proof seal. Capable of handling burst and collapse pressure differentials up to 3000 psi, these screen designs are available in two hole sizes, 380 and 500 micron.
