The Festo MS9 Series Pressure Regulator provides all functions for the preparation of compressed air: valves for pressure regulation, shut off, filter regulation, and soft start, with safety function. It provides good regulation characteristics with minimal pressure hysteresis and primary pressure compensation. 

The pressure regulator maintains an essentially constant output pressure, independently of pressure fluctuation sin the system and air consumption. The output pressure can be set within the pressure regulation range either manually using the rotary knob or pneumatically via pilot pressure, by an external pilot regulator. When the operating pressure is switched off, the output pressure exhausted via port 3 (secondary exhausting).
