This miniature shuttle valve is only .187” in diameter and .84” in length. The poppet in this shuttle valve is biased so that the emergency port (E) is normally closed, and the normal (N) and service (S) ports are connected. It is ideal for applications with flow rates up to 1.3 gpm. The valve has integral safety screens for added protection against rogue contamination or debris.

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.
