The Lee Company, Industrial Microhydraulics Group

The Lee Company offers many of it’s precision fluid control products already installed in appropriately sized flared, flareless, or dynamic beam seal unions. Lee also offers an array of higher pressure Restrictors, Valves, and Safety Screens built directly into convenient Ring Locked Adapters, allowing designers to take advantage of the unused space in the adapters to reduce manifold size and weight.

IMH Insert Precision Orifices are economical, reliable, highly accurate miniature flow restrictors. They are available in 2.5mm, 5.5mm and 8.0mm body diameters, and in forward and reverse flow versions. All three sizes are available in liquid and gas versions. Integral safety screens are incorporated where the orifice diameter is 0.5mm (.020") or below.

IMH Precision Orifices for plastics are economical, reliable, highly accurate miniature flow restrictors. They are available in a 2.5mm body diameter, and in forward and reverse flow directions for both liquids and gases. These orifices are 100% flow tested to ensure that every orifice is within ± 5% of its nominal flow rate. Tighter tolerances are available as specials.

IMH Pressure Relief Valves for plastic installation have the same internal design as the Insert Pressure Relief Valves, but feature easy, press-in installation. A high quality, metal to metal seat provides low leakage and highly repeatable cracking pressure as well as compatibility with a wide range of fluids and gases.

IMH Insert Flow Control Valves are, functionally, an orifice in parallel with a check valve, all in one compact, cartridge-style package. These valves are available in two diameters; 5.5 mm and 8.0mm. Both sizes are available in forward and reverse flow directions.

IMH Insert Pressure Relief Valves are threadless, cartridge-style valves designed for simple, low-cost installation into manifolds, in the most compact package available anywhere. A high quality, metal-to-metal seat provides long life and extremely low leakage, as well as compatibility with a wide range of fluids.
