This miniature shuttle valve incorporates a polyimide valve seat to create a leak tight seal when tested on nitrogen. It incorporates a detent mechanism that can latch the poppet at either of the inlet ports, making it helpful when bi-directional flow is needed in either poppet position. This valve is ideal for applications with flow rates up to 13 GPM and is rated for operating pressures up to 5000 psid.

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.
