Capabilities in miniaturisation and engineering expertise keep the company at the forefront of fluid flow technology.
Precision Microhydraulics
Check Valves
Check Valves
A wide variety of miniature, pre-tested cartridge check valves that offer proven reliability and performance.
Shuttle Valves
Shuttle Valves
Miniature, 3 port, hydraulic valves that allow fluid to flow from one of two inlet sources to a common outlet.
Pressure Relief Valves
Pressure Relief Valves
Pressure Relief Valves are specifically designed to be the smallest valves available for safety relief applications.
Electro-Fluidic Systems
Solenoid Valves
Solenoid Valves
Lee Products manufactures 3 basic types of solenoid valves: control valves, dispensing valves and isolation valves.
Dispense Pumps
Dispense Pumps
Lee Products manufacture 2 different kinds of dispense pumps: fixed volume dispense pumps and variable volume dispense pumps.
Custom Manifolds
Custom Manifolds
PManifolds offer several advantages compared to just tubing together discrete components, such as fewer leakage points, lower internal volumes, easier assembly into the instrument, and higher reliability.
