Description

The Lee Company manufactures a wide variety of miniature, pre-tested cartridge check valves that offer proven reliability and performance. With almost one million valves successfully in service, some for over 20 years, Lee check valves set the standard for small size, light weight and proven reliability. Four types of miniature check valves are available: Axial Flow Check Valves Side Exit Check Valves Zero Leak Check Valves Pilot Operated Check Valves Lee Chek® Ø 0.187 and a 0.250 inch diameter ball-type check valves designed for 3000 psi systems and available screened and unscreened, forward and reverse flowing.
