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

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.
