Flow Metering Valves

Insert style flow control valves are comprised of a precision orifice in parallel with a check valve, combined into a single component. Each is designed for easy installation into metal housings using our field-proven locking end, which provides retention and a leak-tight seal without the use of threads, O-rings, or custom in-house designs. Its all-stainless-steel construction and high-quality metal-to-metal seat result in a repeatable cracking pressure and a long life. Each valve is 100% tested to ensure that all parts are within their flow tolerance. These valves are available as standard models in 5.5 mm and 8.0 mm diameter (which offers more free flow) envelopes. Each can be purchased in a variety of Lohm rates and in both forward and reverse configurations.

Press-in style flow control valves are comprised of a precision flow orifice in parallel with a check valve, combined into a single component. Each part is designed for easy installation into plastic housings, fittings, and tubing using our unique barbed design that ensures retention and eliminates bypass leakage. The press-in-style valves are constructed of all stainless steel and a high-quality metal-to-metal seat provides repeatable cracking pressures and long life. Meanwhile, each component is 100% flow tested to ensure that all parts are within their flow tolerance. The Lee Company offers two standard models of flow control valves: 5.5 mm and 8.0 mm diameter (which offers more free flow) envelopes. Each model is available in a variety of Lohm rates.
