Outboard Bearing Rotary Valve (OBRV)

High efficiency airlock

The Outboard Bearing Rotary Valve (OBRV) is a high efficiency airlock with minimum leakage blow-back. Outboard bearings provide the airlock with maximum

bearing support.

The OBRV is designed with shaft braided packing seals that are most frequently used where product contact could damage the seals and cause bearing failure.
