This product is used on chromatographs, mechanical seals, chemical injection, blending systems, instrument purge systems, natural gas, Nitrogen generation, Bleaching systems, and hundreds more.

How It Works

The Micro-Flo combines a characterized needle valve with an internal differential pressure-regulating valve. By controlling the pressure drop across the adjustable orifice, flow rate will always remain constant. Since the control portion is immersed in the fluid it is controlling, response time to pressure variations is immediate and hunting or oscillation is eliminated.

Easily adjust your flow setpoint by turning the micrometer-like needle valve adjustment. Once set, the Micro-Flo will control your flow accurately, regardless of changes in your process.


Did you know???

It is rather ordinary for us to come across a Kates controller in the field still functioning after 40, 50 or even 60 years.
