Kofloc Constant Flow Valve for Liquid MODEL 2600S & PVC Series

Constant Flow Valve for Liquid

MODEL 2600 SERIES

This is a constant flow valve developed for liquids, and maintains a constant liquid flow irrespective of pressure changes on the primary and secondary sides.

Features

1.Excellent constant flow valve for liquids
   The valve is made of high-precision parts for smooth control.

2.Immune to pressure changes
   The valve keeps the flow constant irrespective of changes in the primary- and secondary-side (outlet-side) pressure.

3.Control of very small flow from 10 ml/min

4.Upper and lower diaphragm chambers equipped with airbreathers
   Air breathing during initial flow setting permits high accuracy control.

Applications

1.Analyzers
2.Environmental measuring instruments
3.Liquid mixing equipment

Note: The control accuracy is guaranteed only when the fluid temperature is constant,

because the viscosity varies with temperature.
