The Lee Company’s Dual Metering Flow Control Valves are two way restrictors that allow designers to specify a different metered flow rate in each direction. Configurations are available for system pressures up to 5000 psi. Each valve is 100% tested in both flow directions to ensure reliable, consistent performance. Featuring an all-stainless steel construction for durability and long life, models are available in 0.187 inch and 0.281 inch diameters.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
