The Siemens Miniature Pressure Regulator is a compact, precision-engineered device built for reliable low-pressure air control in industrial and analytical environments. With a maximum inlet pressure of 250 lb and an adjustable 0–60 PSI outlet range, this regulator provides stable, repeatable control over airflow to instrumentation and process equipment.

Designed with ¼” NPT inlet and outlet ports, plus two (2) auxiliary 1/8″ NPT outlet ports, this unit supports easy panel integration and downstream accessory connections. Its non-relieving design prevents exhaust leakage, making it suitable for clean, controlled systems where venting cannot occur.

This regulator is frequently used in air heater/oven control loops, combustion support, and analytical laboratory equipment such as FID (Flame Ionization Detectors) and FPD (Flame Photometric Detectors), where consistent air delivery is critical to measurement accuracy.
