High Flow Check Valves

As the name suggests, Lee Bender Jets use multiple offset orifices in series. Each additional restriction causes an increased reduction in flow. This produces an effect that results in an increased minimum passage size for a given Lohm rate. The valve’s components are protected with two integral safety screens for bi-directional flow and are available calibrated to a ±5% tolerance in the range of 125 to 9500 Lohms.

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.

For advanced applications, aircraft and defense manufacturers may wish to consider Lee Floserts. This is a pressure compensated flow control − in other words, the flow will remain constant across a wide range of differential pressures. A variable metering orifice automatically adjusts by sensing the flow rate in terms of differential pressure across a fixed orifice. Floserts are available with the Lee locking end for installation in diameters from 0.250 to 0.500 of an inch as well as a 0.687 inch threaded configuration. Also available are metered flow rates from 0.01 GPM up to 5 GPM, as well as high-pressure versions for operating pressures up to 5000 psi.
