Kofloc Model 2600S/2600PVC 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.

A needle valve is the typical flow control valve that controls the flow rate based on the change of resistance of the flow channel using an acicular or rod-shaped needle to adjust the opening of the flow channel that functions as a small orifice. KOFLOC offers simple-type, precision-type and various other needle valves, and also manufactures flow controllers having a combination of a needle valve and diaphragm as well as proportional solenoid valves that electrically control the flow rate.

KOFLOC strives for thorough quality control at domestic factories. In recent years, we have also been focusing on product development for liquid measurement and control equipment, and we will deliver products that can be trusted as “Fluid Kofloc” to the world.

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 the initial flow setting permits high accuracy control.

Applications

Analyzers
Environmental measuring instruments
Liquid mixing equipment
