Custom normally-open valves that close above a specified flow rate
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. Custom flow fuses are available in .187, .281, .483, .798 and 1 inch diameters with shut-off flow rates tailored to meet application needs.
