This miniature, pilot-operated check valve is only 0.25 inches in diameter and 1.25 inches in length. The valve acts like a normal check valve until pressure is applied to the pilot port, at which point the valve allows flow in the direction that would normally be blocked.

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.
