Rexroth’s long-service-life Ceram valves feature ceramic plates designed for basic sealing, excluding such environmental contaminants as corrosion, dust, dirt and sand, which can end up in an air line. These contaminants accelerate wear and cause failure of rubber seals. The ceramic plates, one static and one dynamic, are made of extremely hard aluminum oxide and form a nearly perfect seal. The top ceramic plate slides against the bottom static plate, causing a self-cleaning action as the valve shifts, and slots in the plates direct airflow as the top plate is shifted. These plates do not suffer from the sticking problem to which rubber seals are prone.
