  • Product Description

  • 　　Explanation

    　　The Cobra series regulators deliver superior performance and consistent pressure output. These products boast an extended service life and are ideally suited for applications requiring controlled emission of pollutants. Their distinctive pin design and fluorosilicone diaphragm provide optimal resistance to over‑pressurization while enabling operation at low temperatures. A standard blue secondary spring delivers a negative pressure of 1.5 inches w.c. (0.37 kPa), while an optional yellow secondary spring provides a negative pressure of 0.5 inches w.c. (0.12 kPa).
