Vacuum Valves
A well designed and operated vacuum system for the wet end helps achieve better paper quality
and reduces power consumption.
Coldwater’s self-regulating vacuum valves are specially designed to quickly adjust to changing
conditions to keep the vacuum constant. The valves use air pressure in a double diaphragm chamber
to maintain an instantaneous balance, giving much faster response than a ball or butterfly valve.
Uncontrolled vacuum can cause two-sidedness, poor formation, pin holes, bad retention and
significant waste of power.
Coldwater Tech Services can evaluate and make recommendations to improve wet end operations.
We have trained specialists in headbox operation and maintenance, drainage and formation,
vacuum capacity and energy use, and edge control who gather and analyze objective data and then
present recommendations in a clear and concise format.
