Large Capacity Back Pressure Valve
MODEL 6801 SERIES
A back pressure
valve is a kind of relief valve to obtain a constant level of pressure in
the first stage of valve operation. This
type of valve makes it easier and speedier for the user to control pressure in the tank with a large buffer, purge a given quantity of mixed gas or to carry out
such other operations which are rather
hard to do with a secondstage control
valve commonly in use.
