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
