General Description

Series DHV-S-DL backpressure valves serve the purpose of
creating a constant backpressure to ensure exact media feed rates
and to protect against overloading while also increasing the
metering accuracy when metering against atmospheric pressure.
Installation in metering line.
They are also suitable for use together with pulsation dampers to
facilitate low-pulsation metering.
Used as overflow valves (pressure relief) in bypass systems, they
protect pumps, lines and fittings from overpressure as the result of
incorrect operation or blockages.
DHV-S-DK backpressure valves serve the purpose of creating a
constant backpressure to ensure exact media feed rates and to
protect against excess metering while also increasing accuracy
when metering against atmospheric pressure. Installation on top
of metering head.

Safety

Intended use

• The backpressure valves are intended for use with liquid media
only.
• The backpressure valves serve the purpose of creating a
constant backpressure.
• The DHV-S-DL backpressure valves serve the purpose of
facilitating low-pulsation metering when used together with
pulsation dampers.
• The DHV-S-DL backpressure valves may be used as overflow
valves in bypass systems.
• The DHV-S-DK backpressure valves may only be used for the
purpose of preventing overloading when metering against
atmospheric pressure.
• All other uses or conversions are prohibited!
• The backpressure valves must not be used together with
gaseous media or solids!
• The backpressure valves must not be used in conjunction with
liquid media that corrodes its materials (refer to ProMinent
chemical resistance list in the product catalogue)!
• The backpressure valves must not be used outside the ambient
and operating conditions as specified in these operating
instructions (e.g. P-T diagram!)!
• Ensure only personnel trained and authorized for this purpose
operate the backpressure valves!
