Cobra Regulator
The Cobra regulator/vaporizer delivers superior performance and excellent pressure output consistency. Cobra offers greater service life and is ideal for applications with controlled emissions. Its primary pin design and fluorosilicone diaphragm offer superior chemical resistance, resistance to over pressurization, and cold weather operation. Use of the standard blue secondary spring provides -1.5" w.c. (0.37 kPa). The optional orange secondary spring provides -0.5" w.c. (0.12 kPa) output.
