High Flow Relief Valve

The High Flow Relief Valve is designed to quickly move large quantities of air and automatically prevent pressure build-up in container packaging applications. Offering both pressure and vacuum relief at an opening point of 0.5 psi ± 0.25 psi in both directions for fast or explosive decompression, it protects the goods inside from extreme pressure. It also allows for safe access to the application.

Perfect Substitute from Rupture Disks

However, commonly used to protect applications from overpressurisation, Rupture Disks are one-use devices that require replacement once used or over-pressurised. On the other hand, the High Flow Relief Valve, with a flow rate up to 140 SCFM, can provide the rapid decompression needed (depressurising a typical cargo hold in 15 seconds) and is reusable.

Best Protection from Atmospheric Pressure

Even without an immediate decompression requirement, airborne transport of large volume containers requires large volumes of moving air to prevent explosion or implosion resulting from atmospheric pressure changes with altitude. For a container of over 1,100 ft.³, one High Flow Relief Valve is sufficient for atmospheric pressure protection.

Easy to Use

The High Flow Relief Valve has a manual release button that ensures safe and easy entry into the enclosure under vacuum conditions or pressurised. A retaining clip is secured to prevent the button from being misused, while the lanyard attached to the clip prevents it from being lost. It projects 1.25″ from the container wall to the tip of the manual release button. The valve is not only low profile but also easily installed into container walls up to 1/2″ thick.
