Automatic Breather Valves for Containers

In order to protect sealed containers from the harmful effects of pressure changes it is essential to fit a reliable and effective pressure and vacuum relief devices. Our range of Automatic Breather Valves are purposely designed for use on transit, stowage and missile containers to meet all the requirements for air transportation.

We offer a complete range of automatic breather valves, from pressure relief, vacuum relief or two-way, double differential valves. The valves require no field maintenance and are tamper-proof, in many cases Desiccant Cartridges can be fitted to allow moist air entering the container to be dried, alternatively Desiccant Bags can be used in conjunction with a Desiccant Port.

Most Automatic Breather Valves have a manual release button which will equalise pressure or vacuum differentials before opening your container. There are a range of pressure settings available from as low as 0.25psi up to 10psi. Typically, with Container Automatic Breather Valves they are set to a reseal pressure to enable them to hold a maximum pressure within the container. Equipment valves generally have a crack pressure, so the valves are opening at a specific setting.

We also offer a range of Conductive Nut & Shielded Nut assemblies that can be used in conjunction with the Automatic Breathers Valves to provide RFI / EMI conductivity.

If additional filtration is required for your container, we offer a range of High Flow Filter Assemblies that can be mounted to the rear of the Automatic Breather Valves. These High Flow Filter Assemblies are fitted with HEPA (High-Efficiency Particulate Arresting) filters that can remove particles to a nominal 0.3 microns.

For valves used on more sensitive products like electronic and electro-optic equipment’s, please see our range of Equipment Valves.
