To maintain and regulate top pressure on pressure tanks during
filling, processing and emptying.
The pressure regulator comprises a single valve unit including
pressure relief valve, pressure supply valve, and connection
for pressure gauge. On top is a vent port with outlet connection.
Modular design to suit different requirements.
Valve block and vent port: Stainless steel AISI 304
Valve bodies (as standard): PP and stainless steel with
All other parts: Non-toxic foodgrade materials.
The correct sizing depends on gas volume to pass during filling,
fermenting, or emptying. The table below can be used as
a guideline for standard fermentation.
Dimensions Filling/emptying Working capacity
speed of fermenter
1 / DN 25 Max. 250 hl / h Max. 1000 hl
11⁄2 / DN 40 Max. 500 hl / h Max. 2000 hl
Pressure regulators in size 2, 3 and 4 are available in
another version (see separate PD leaflet).
Standard operating pressure ranges up to 3,0 bar/ 43,5 psi/
The pressure regulator is available with spring regulation in
Fixed setting (one pressure only)
The pressure regulator is produced with weld type ends, but
can be delivered with threaded connections to suit customer
specifications, i.e. BSP, NW, RJT, IDF, DS or Tri-Clamp.
Constant tank top pressure during filling, processing and
Reliable setting of working pressure
Fully cleanable with CIP system
When the valve unit is supplied with variable setting the relieving
pressure is adjusted to the required working pressure
in the tank.
When tank top pressure exceeds preset pressure (e.g. during
filling or fermentation) gas leaves the pressure regulator
through the vent port either for atmospheric discharge or for
If the tank top pressure decreases (e.g. during emptying) gas
is supplied through the gas supply connection at the bottom.
The pressure regulator is easily incorporated in the tank CIP
procedure by means of the CIP adaptor.
Before cleaning the CIP adaptor is mounted on the pressure
regulator whereby gas supply valve and pressure relief valve
are forced open and fully cleaned in bypass.
Important: During the CIP procedure all functions are
Tank connection at side branch is normally connected to the
pipe leading to the tank top. Optionally it is connected with
extra support by means of bracket fixed on reverse side of
It is also possible to incorporate the pressure regulator in a
When included in CIP procedure - periodic disassembling to
check the internal appearance and the condition of valve
bodies and joints is necessary. Gaskets and O-rings to be
replaced approx. every 2-3 years.
CIP adaptor (T-piece and 180° bend)
Protection valve for pressure gauge is used when CIP pressure
exceeds range for pressure gauge.
