Flow Metering Valves

558 Series Flow Control Valve

The 5.5mm Insert Flow Control Valves are, functionally, an orifice in parallel with a check valve, all in one 5.5mm diameter, cartridge-style package. These valves are threadless and designed for installation into metal manifolds. They utilize The Lee Companies field-proven insert principle that provides secure retention without the need for threads, O-rings or sealants. The valves are all stainless steel construction with a high-quality metal to metal seat providing highly repeatable cracking pressures and long life. All valves are 100% flow tested for consistent batch to batch performance.
