MS61-7203 TAC DuraDrive™ Linear Series Spring Return Actuator 24V, 2-10 VDC, 220 lb.


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.


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
