Product Overview
The Rexroth MAR11U 4.5 (Part No. 178263) is a precision pneumatic pressure regulator engineered for accurate downstream pressure control in industrial compressed air and neutral gas systems. As a member of Rexroth’s MAR series of process and pneumatic valves, this unit utilizes a diaphragm-actuated, spring-loaded regulating mechanism to maintain a stable outlet pressure regardless of fluctuations in inlet pressure or flow demand. The regulator features a 4.5 bar outlet pressure range and is designed for panel or inline mounting within pneumatic control circuits, offering reliable pressure regulation for actuators, air preparation units, and process control loops. Its balanced poppet design ensures minimal pressure drop and consistent performance across the full operating range, making it a dependable component for demanding industrial environments.
