The 703 two-way breather valve is identical to the 702 breather valve with the addition of a manual relief feature that allows the user to equalize a pressure or vacuum to aid in opening the container.
With over 100 cfm of flow at only 0.4 psi, the 703 two-way breather valve is used on large shipping containers to protect equipment from moisture ingress as well as to protect the container from damage due to excess pressure and vacuum. Some applications include lightweight, air-transportable aluminum and fiberglass shipping containers.
One valve is sufficient for a container with an internal volume of 866 ft3 that can withstand a pressure differential of 0.4 psig.
