micro-machined RB® Valve performs two critical functions, and stays out of harm's way.
Automatic RB® Valve provides continuous pressure
relief while also functioning as a check valve. By installing one
on each desiccator chamber, you ensure that any contaminants that
enter through an open door exit out the same chamber and don't migrate
to other areas.
desiccators use either oil valves, which can contaminate a clean
environment, or bulky valves that protrude from cabinets and are
subject to impact damage. Terra's latest RB®Valve
protrudes less than .5" (127mm) from the chamber wall. It is designed to
fit against the hinge reinforcement bar, so it can't be sheered
