NSPW, NFFW & NFF-S Series Constant Flow Valve
Brand: Tokyo Keiso Co, Ltd
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.
