Constant Flow Valve for Liquid
MODEL 2600 SERIES
Features
Flow not affected by variations in inlet and outlet pressures with an operating differential pressure left
No instability of flow and control by bubble mixture
Capable of stable control by pulsation preventive design
Capable of control from a range of 1 to 10 ML/MIN
By installing a bubble discharging valve, bubbles can be discharged in a short time during start-up to make stable control.
Bubbles need not be discharged once they are discharged during start-up.
