Product Overview
The NORGREN 11-818-938 is a precision pneumatic pressure regulator engineered for accurate downstream pressure control in compressed air and inert gas systems. As a member of NORGREN’s proven 11-818 series, this regulator utilizes a balanced poppet and diaphragm sensing mechanism to maintain a stable outlet pressure regardless of fluctuations in inlet pressure or flow demand. Its self-relieving design allows excess downstream pressure to vent automatically, protecting sensitive pneumatic instrumentation, actuators, and process equipment. The unit is a direct-acting, manually adjustable regulator intended for panel or line mounting in industrial air preparation and control circuits.

Engineering Features & Advantages
- Precision Performance: Balanced poppet and diaphragm design delivers accurate, repeatable outlet pressure regulation with minimal droop across varying flow rates.
- Self-Relieving Operation: Automatically vents excess downstream pressure, safeguarding instrumentation and preventing over-pressurization of pneumatic circuits.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with robust housing and wear-resistant internal components.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original NORGREN OEM standards, ensuring drop-in serviceability.
- Stable Output: Maintains set pressure despite inlet pressure fluctuations, supporting consistent actuator and process performance.
Typical Industrial Applications
Ideal for compressed air preparation in plastic injection molding machines, packaging and assembly lines, CNC machine tools, pneumatic actuation and control panels, and general factory automation where stable downstream pressure is critical. Also suited for instrumentation air circuits, valve pilot supply, and process gas regulation in metallurgical, marine, and heavy manufacturing environments.
