Kofloc Backpressure Valve Model 6800 Series

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.

Features

-Convenient panel-mount type

– Compact design

– High-speed regulation of primary-side pressure

– This greaseless clean valve permits gas control in a pure state.

Applications

– Tank pressure control

– Constant flow control of mixed gas
