Check valves:Effective protection for your equipment
No way back for air and gases
In process engineering systems, sudden flow reversals after compressors and in connecting pipe
work pose considerable risks for the system, compressors and personnel. HOERBIGER check valves
offer effective protection against this risk.
The solution for critical applications:
Based on many years’ experience in the
field of valve technology, HOERBIGER
has developed the right solution for just
such critical applications.
Even in strongly pulsating flow environ-
ments and under varying operating con-
ditions, the HOERBIGER check valve is
reliable, safe and efficient.
HOERBIGER check valves have proven
to be the right solution in countless
applications
with compressors
� Refineries
� Petrochemical industry
� Chemical industry
� Natural gas industry
� Industrial air systems
� PET production
in piping
� all industries
Critical pulsations and strong
fluctuations in flow conditions after
controlled compressors are a particular
challenge for check valves.
This means the check valves have to
adapt to the prevailing pulsations,
turbulences and changes in inflow
conditions and close quickly and
reliably upon sudden flow reversal.
Fast, reliable, safe and efficient
Valve in housing type A engineered and optimised
HOERBIGER check valves are custom
solutions matched perfectly to the
application, ensuring optimum opera-
tional characteristics with minimum
pressure drops.
efficient and reliable
The uniform system of valve discs and
springs moves in harmony with the
pulsations and turbulences. The special
design of the internal parts reduces
the movement of the sealing element
and leads to significant pressure relief
during the opening and closing cycle.
HOERBIGER check valves are the solution
for both normal and critical applications.
HOERBIGER check valves are
responsive
The low-mass and friction-free valve
discs allow the valve to open and close
rapidly and reliably, even with low flow
rates. This is particularly important with
controlled compressors because the entire
control range is covered and the valve is
responsive and reliable even when the
compressor flow rate is low.
problem-free and safe
The proven design and application-
matched metals ensure smooth and
efficient operation in any situation,
even in highly corrosive applications.
The friction-free valve discs result
in barely any wear, which makes for
extremely low maintenance
requirements.
