CAUTION
• System components may burst if the setting pressure is
adjusted too high!
The setting pressure P
always be lower than the maximum permissible operating
pressure P of pulsation dampers, pumps and line systems.

• Please note that hazardous situations can arise when the
backpressure valve has not yet been set in the system and
the shut-off elements are opened or the system is started
up! Take the necessary precautions!
NOTE
The setting pressure P at the backpressure valve must always be
E
greater than the admission pressure P
pressure ∆P resulting from mass deceleration (∆P is approx. 1.5 bar
in standard lines up to approx. 3 m).
The admission pressure P1 as the result of the height h is

CAUTION
• The backpressure valve must be set under the same
operating conditions as it will be subsequently used!
Never set the valve on a test rig and then install it in a
system! (Also observe the viscosity of the metered medium!)
