Emerson Fisher's C477G Series (Straight Through Body) Jet Bleed Internal Valve is the most compact and economical unit in the series. The C477G Series has one bottom outlet.
These valves 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.
Note: This model has a stainless steel straight body with low temperature nitrile trim.
