Kofloc Control Valve 2600S 2600PVC Series

Constant Flow Valve for Liquid

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

• Excellent constant flow valve for liquids

The valve is made of high-precision parts for smooth control.

• Immune to pressure changes

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

• Control of very small flow from 10 ml/min

• Upper and lower diaphragm chambers equipped with airbreathers

Air breathing during initial flow setting permits high accuracy control.

Applications

• Analyzers
• Environmental measuring instruments
• Liquid mixing equipment

Note *1: The control accuracy is guaranteed only when the fluid temperature is constant,
because the viscosity varies with temperature.
