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.
Features
– Handy panel mount type
– Quick regulation of primary pressure
– Greaseless, clean valve perfect for control of pure gases
Applications
– Tank pressure control
– Control of constant flows of mixed gases
