The Automated Kates Flow Control Valve will improve the performance of almost any control loop.
Regardless of pressure fluctuations, the Kates will control the flow rate proportional to the 4-20 mA input.
Flow output is perfectly linear to signal input. By internally maintaining a constant differential pressure across a metered orifice, flow control is maintained to within 1½% of set point.
A variety of electric and pneumatic actuation control signals are available.
