SKB 3SKB Automatic Pressure Relief Valve

Manage pressure differences between the interior of a compatible equipment case and the surrounding environment with an automatic pressure relief valve. This component is intended for SKB 3i, 3R and Shock Rack cases, where pressure equalization matters when cases move between different elevations or environmental conditions. Its automatic operation avoids a manual venting step when the case is closed. The valve is a case-service component rather than a carrying case, rack enclosure or mounting accessory. Use it where the existing case design calls for an automatic relief valve and compatibility with the 3i, 3R or Shock Rack case families is required. It supports maintenance of protective equipment cases used for transported electronic equipment, instruments and other enclosed hardware. SKB 3SKB-V5 identifies the orderable version of the 3SKB automatic relief valve. The product’s stated family coverage is its key selection detail: it fits 3i, 3R and Shock Rack cases. Verify the valve location and required replacement configuration on the specific case before installation, particularly when servicing a case that has been modified or repaired previously.
