Automatic RB^® (Relief/Bleed) Valve

	No. 1600-60 For use with caustic materials   No. 1600-60A actual size: 1" x 1" x 2" (25 mm x 25 mm x 51 mm)

• Continuously bleeds off excess internal gas to maintain a safe positive pressure inside glove boxes
• Variable release mechanism automatically discharges any sudden surge of incoming gas
• Protects against accidental negative pressure by functioning as a check valve
• Extends life of doors and gaskets
• 100% reliable, noncontaminating and maintenance-free! The Automatic RB® Valve ensures a safe, continuous positive pressure in Terra Universal glove boxes, desiccators, and other purged enclosures.

It provides three crucial functions. During normal operation, it allows a continuous low-level release of gas to maintain a safe internal positive pressure. In the event of a sudden increase in the incoming gas supply, it automatically opens to relieve the high pressure. Finally, it functions as a check valve to ensure that air and contaminants cannot enter the enclosure in the event of a momentary negative pressure.

Most important, it provides operator peace of mind. Its field-proven reliability guarantees that your cabinets maintain a safe positive pressure, even when subjected to a high-flow of purge gas. It also safeguards your investment in a processing chamber by preserving doors and seals.

Select the Static-Dissipative PVC model for use in Terra's glove boxes. The compact size makes it ideal for mounting either internally or externally. The static-dissipative PVC material resists a wide range of process gases and chemicals and will not generate surface charges, an important consideration in static-sensitive applications.

For effective pressure relief select one valve per air lock, up to 8 cu. ft. (0.2 m³) and two valves per glove box, up to 45 cu. ft.( 1.3 m³)

Stainless Steel Design for Caustic Gas

Both models come with all necessary mounting hardware. Installation is included if ordered with glove box.
