Cooling Water Flow Regulators
The essential equipment
for every injection and blow moulding machine
Worldwide the leading Water Flow Regulators
used by most of the European machine manufacturers
Why you should use Wittmann Water Flow Regulators:
- Instant indication of blocked mould cooling circuits avoids producing bad parts.
- Consistent part shrinkage through precise, repeatable mould temperature control.
- Adjustable sight tube rings show flow deviation, allow fast flow settings.
These are the best built, most reliable
Water Flow Regulators available!
Here’s what our competitors don’t want you to see:
Easier to Clean
The Wittmann water flow regulators
are exceptionally easy to clean. A top
access cap is simply removed and a
brush (provided) quickly cleans the
tubes without removing them.
Easier to Remove
Individual sight tubes can be easily removed
and reseated, if necessary. Precision O-rings
positively seal the sight glass, absolutely
leakproof even under maximum loads.
Don’t settle for a plastic cap screw which can
break easily. Ours is all brass.
Housings moulded of reinforced polyphenylene
oxide for tough industrial use.
All units are 100 % leak tested before shipping.
Thermometer is directly in the water flow giving
a more precise reading and a quicker reaction
to changes. Competitor’s thermometers are not
in water flow path.
Competitor’s regulators include a large diameter
valve for the main seat which means regulation
is not precise. With a very small movement of
the handwheel, the valve is opened almost com-
pletely. Our units have a smaller diameter seat
which allows better adjustment of flow.
All brass internal components and floats stand
up to poor water quality.
EPDM O-ring seals are heat and water resistant.
Our sight tube is polyamide 12 which is superior,
compared to competitors polycarbonate, when
higher temperature water is used. Competitors
charge extra for the better material. At our unit
it is standard.
Reference marks are moulded in, not painted on.
