Two Way Relief Valves are designed for transit and storage containers but can also be used for electronic and electro-optics equipments. The valves have separate and distinct settings for both pressure and vacuum relief. Standard settings range from 0.5psid to 3.0psid reseal pressure. These valves are tamper-proof and require no field maintenance. On some of these valves a desiccant cartridge can be fitted to adsorb moist air entering an equipment or container. Most valves have a manual release push button to equalise pressure or vacuum differentials in order to open the container or equipment.
