Automatic RB® (Relief/Bleed) Valve
- 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.
Static-Dissipative PVC Design for Series 100, 500 and 600 Glove Boxes
Select the Static-Dissipative PVC model for use in Terra's Series 100 polymer 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.) and two valves per glove box (up to 45 cu. ft.)
Stainless Steel Design for Series 300 and 400 Glove Boxes
Terra's stainless steel Automatic RB® Valve is designed for use in stainless steel glove boxes (Series 300 and 400). It incorporates a Teflon® valve mechanism that allows a higher rate of gas release, allowing a single valve to safely exhaust any chamber size.
Both models come with all necessary mounting hardware. Installation is included if ordered with glove box. |
