Floating Valve Actuator
Model Chart
The MF-22xx3 and MF-23xx3 series floating valve
actuators are non-spring return actuators used
with floating DDC controllers and standard 1/2 to 2
in. two-way and three-way globe valve bodies for
control of heating and cooling coils. Typical
applications include VAV terminals with reheat
coils, fans coil units, and unit ventilators. Certain
models are thermally isolated for use with chilled
fluids.
Features:
• Floating actuator controlled by DDC controller with contact
or Triac output or SPDT center off controller (drive open-
hold-drive closed).
• MF-22xx3 has 45 pounds (200 newtons) of output force
with automatic load limit for self-adjusting travel and long
motor life.
• MF-23xx3 has 80 pounds (355 newtons) of output force at
low line voltage and requires DDC controller with time-out
feature.
• Synchronous motor for consistent timing.
• Manual override with automatic release.
• Optional feedback potentiometer available for precision
control or position indication.
• Integral linkage for all standard 1/2 to 2 in. TAC two-way
stem-up open and three-way valve bodies for a wide
variety of applications.
• Compact size for application flexibility.
• Rugged construction with die cast housing.
