Backpressure Valve
MODEL 6800 SERIES
The backpressure valve is a kind of relief valve that keeps the
pressure at the front stage of a valve constant. It can easily and quickly control the pressure of a
tank with a large buffer and remove the
constant flow of a mixed gas, which cannot easily be done by general
regulation valves with a subsequent stage
controlling function. This new concept of pressure regulation has been
attracting much attention.
