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

• 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 air-breathers

Air breathing during initial flow setting permits high-accuracy control.
