Description
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
- Integral linkage for direct mount to valves
- Five year warranty
