Fisher Types C471 and C477 Jet Bleed Internal Valves

Fisher™ Types C471 and C477 are typically used on the inlets and outlets of bobtail and transport trucks and on large stationary storage tanks. They can also be installed in-line. Designed for propane, butane, or NH3 at ambient temperatures, the valves can be used on other compressed gases, but the user should check with the factory to make sure the valves are suitable for the particular service.
