MS61-7203 TAC DuraDrive™ Linear Series Spring Return Actuator 24V, 2-10 VDC, 220 lb.
Application
TAC DuraDrive Linear Actuators are designed to mount directly onto two-way or three-way valves. They provide linear travel to economically operate 1-1/4" to 2" VB-7xxx, 2-1/2” to 5" VB-8xxx, 2-1/2" to 4" VB-931x, and discontinued 1-1/2” to 4” VB-9xxx valves in hot water, chilled water, and steam applications up to
366°F (186°C) fluid temperature.
The linear spring return actuators provide either two position, floating or proportional modulation control
(depending on model selection) of valves in HVAC systems.
Features
Two position models controlled by SPST controller
Floating models controlled by SPDT floating controllers
Proportional models controlled by 2-10 Vdc, or 4-20 mAdc with the addition of a 500 ohm resistor. Control function direct/reverse action is switch selectable
220 lb force (979 newton) with 1/2” (13 mm) or 1" (25 mm) nominal linear stroke
Automatically sets control signal input span to match valve travel
24 Vac, 120 Vac, and 230 Vac models
Rugged die-cast enclosures rated for NEMA 2, UL Type 2/IP54
Overload protection throughout stroke
Compact size for application flexibility
Manual override to allow positioning of valve and preload
Integral linkage for direct mount to valves
