■ General description
The constant flow valves are used to maintain
preset flow rate in a line that develops
primary (inlet side) or secondary (outlet
side) pressure fluctuations.
Requiring no control device against pressure
fluctuation, these valves contribute to
savings in space and cost. Especially, they
offer best suited and handy use with cooling
and hot water lines of air conditioning systems
in buildings and water supply lines in
plants and multiple housing.
Also, as the valves need no power supply to
operate, they are safe against highly flammable
and hazardous fluids. They are accurately
set for necessary flow rate to the
customer’s specification in the factory before
shipment so that no field setting is required.
