1 About This Product
Back pressure valves belonging to the DHV-U
product range are nearly back pressure-free
piston diaphragm valves with an internal flow.
Therefore they are suitable as back pressure
valves even when there is a fluctuating back
pressure.
The back pressure valves are used to create a
constant back pressure to ensure precise feed
rates and to protect against over-metering or to
increase the metering precision if the back
pressure is fluctuating or when metering into
atmospheric pressure or a vacuum.
Used as relief valves in the bypass they limit
the pump operating pressure.
A manometer can be installed on the back
pressure valves DHV-U M.
The back pressure valves are also available in
FDA-approved versions.
