Lee Visco 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.

Extreme Environment Check Valves
If you need a check valve that can withstand working pressures up to 15,000 psi and operating temperatures of up to 400°F, The Lee Company offers a solution to fit your needs. These valves are constructed of corrosion-resistant stainless steel and are available with multiple polymeric valve seat material options to achieve zero leakage in the checked direction under extreme hot or cold temperatures.
Selective Shuttle Valves
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.
Spring-Biased Shuttle Valves
This valve configuration is typically used to select between the main hydraulic system and the emergency backup that’s biased in the normally closed port. Its non-interflow design means that its three ports are never open simultaneously. These valves can also be used to extend a large unequal area actuator, where reduced actuation force may be permissible in one direction. Lee spring-biased shuttle valves are available in sizes from 0.187 to 0.500 of an inch.
