Flow Fuses
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.

Dual Metering Flow Control Valves
The Lee Company’s dual metering flow control valves are two-way restrictors that allow a designer to specify a different metered flow rate in each direction. These valves are ideal for high-pressure hydraulic applications with system pressures up to 5000 psi. They feature all stainless steel construction for durability and long life and are available in 0.187 and 0.281 inch diameter models. Each Lee Dual Metering Flow Control is 100% tested in both flow directions to ensure reliable, consistent performance.
Because each direction can be specified differently, our dual metering flow controls can achieve a nearly infinite combination of metered flow rates. As such, all of these components are supplied as custom items to meet the specific needs of an application.

Spray Nozzles
Lee Spin Jet® spray nozzles utilize unique vortices and flow passages to provide a finely atomized 70° hollow cone spray pattern. The Lee Company has state-of-the-art equipment to analyze spray patterns and droplet size to determine performance across different fluids, pressures, and temperatures. Standard options are available from 6000 to 18,000 Lohms, each with a safety screen to protect against rogue particles. The nozzles are rated for operation at service temperatures up to 700°F (371°C) max and for continuous service up to 400°F (204°C) max.
Safety Relief Valves
Safety relief valves are designed to be fast-acting components that protect systems with the potential for sudden pressure spikes. These valves may sit dormant for indeterminate amounts of time before needing to be used, so it’s crucial that they always work as intended. Our safety relief valves are available in low-leak and tight hysteresis configurations. To ensure reliable operation, we 100% test each component for crack, flow point and reseat pressure.
Our safety relief valves are available in 0.187, 0.250, 0.281 and 0.375 inch insert diameters and 0.687 inch threaded configurations. They are constructed entirely of stainless steel and are available screened and unscreened. Built-in damping ensures quiet operation. Cracking pressures ranging from 20 to 5900 psid.
