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.
The 5.5mm Press-in 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 designed for installation into plastic housings and fittings or soft tubing. Their unique barbed design provides easy “press-in” installation ensuring retention and prevents any by-pass leakage around the valve. The valves are all stainless steel construction providing compatibility with a wide range of fluids and gases and contain a high-quality metal to metal seat for highly repeatable cracking pressures and long life. All valves are 100% flow tested for consistent batch to batch performance.
