High Flow Pressure Relief Valve

Lee flow fuses are individually designed to meet custom requirements. The valve design functions as a normally open check valve. As the flow rate increases beyond a specified value across the valve, a poppet shuts against the valve seat and stops the flow. Valve materials are typically stainless steel but can be tailored to specific requirements. Lastly, our flow fuses are suitable for system pressures up to 15,000 psi.

Insert-style flow fuses are available in 0.187, 0.281, and 0.375 inch diameters with the fused flow direction available in forward and reverse. Cartridge-style flow fuses are available in 0.295, 0.483, 0.798, and 0.989 inch diameters. A zero leak version using an elastomeric seal is also available.

For more demanding applications, our high flow solenoid valves are available in 2-way, 200 Lohms, and 3-way, 300 Lohms configurations. Both are two-stage poppet designs in a miniature package. These valves are available in normally open and normally closed and single or dual coil configurations for 3000 psi system pressures.

Virtually all Lee miniature components, including check valves, flow controls, restrictors, and screens, are available already installed or built into Ring Locked Adapters. Design engineers can now take advantage of the unused space in their Ring Locked Adapters to save space and weight in their manifolds.

The Lee Company offers all these products in Ring Locked Adapters with three different tube ends: dynamic beam seal, flareless, and metric dynamic beam seal (8° 30’ lip-seal). Dynamic beam seal and flareless tube versions range in size from −4 to −10 (1/4 to 5/8 inch) and metric lip-seal versions range from 6 to 16 mm nominal tube O.D. Titanium has been selected as the adapter material for the lowest possible weight. All Ring Locked Adapters containing Lee components have blue lock rings to distinguish them from ordinary adapters, and permanent external marking to identify the function of the product inside.
