The DH/D9146 Breather Valve fills the need for a low cost, but higher flow valve than the DH/D8887 Breather Valve. The valve can be used on transit cases and similar applications up to 33 cubic feet in volume. It has a flow rate of 4.0 scfm and is available in settings from 0.5 psi to 5.0 psi.

The valve is lightweight, rugged, tamper-proof and requires no field maintenance. Corrosion-resistant materials are used throughout. The valve seal is made of silicone rubber. A recessed manual release push button is standard on all Breather Valves Versions. It is used to equalize residual pressure or vacuum differentials in order to open the container.
