P6400SU-317-250 Technical Data Sheet
Application
Water-side control of heating and cooling systems for AHUs and water coils.
Equal Percentage/ Linear: heating and cooling applications.
Operation
The Electronic Pressure Independent Control Valve is a two-way valve that
maintains constant flow regardless of pressure variations in the system.
Product Features
Provides constant flow regardless of pressure variations in the system.
Maximizes chiller Delta T, preventing energizing additional chillers due to low
Delta T. Simplified valve sizing and selection, no Cv calculations required.

INSTALLATION NOTES
Provide overload protection and disconnect as required.
Actuators may be connected in parallel. Power consumption and input
impedance must be observed.
Actuators may also be powered by 24 VDC.
Actuators are provided with color coded wires. Wire numbers are
4
provided for reference.
Actuators are provided with a numbered screw terminal strip instead of
16
a cable.
IN4004 or IN4007 diode required
Meets cULus requirements without the need of an electrical ground
connection.
WARNING! LIVE ELECTRICAL COMPONENTS!
!
During installation, testing, servicing and troubleshooting of this
product, it may be necessary to work with live electrical components.
Have a qualified licensed electrician or other individual who has been
properly trained in handling live electrical components perform these
tasks. Failure to follow all electrical safety precautions when exposed to
live electrical components could result in death or serious injury.
