This regulator from the CKD Selex lineup reduces supply air to a stable working pressure for cylinders, tools and valves. A diaphragm balances spring force against outlet pressure to hold the setting as demand changes. The modular body connects with filters and lubricators, making it a standard element of machine air preparation units.
