Floating Actuator
Model Chart
TAC DuraDrive Linear Actuators are designed to
mount directly onto two-way or three-way globe
valves without the use of linkages. They provide
linear travel to operate globe valves from 1/2 to 2
in.
VB-7xxx valves and discontinued 1/2 to 1-1/4 in.
VB-9xxx valves, 2-12/ to 4-inch VB-9xxx valves, and
2-1/2 to 5-in VB-8xxx valves in chilled water, hot
water and steam applications up to 366°F (186°C).
Linear spring return actuators provide floating
control of valves in HVAC systems.
Features:
• Floating models controlled by SPDT floating controllers.
• 105 lbf (467 N) with 1/2 in.(13 mm) nominal linear stroke.
220 lbf (979 N) with 5/8-in. (16 mm) or 1-1/16-in. (27m mm)
linear stroke.
• 24 Vac, 120 Vac, and 230 Vac models.
• Rugged die-cast or polymer housings rated for up to NEMA
2/IP54 rated for plenum use.
• Polymer housing rated for plenum use.
• Overload protection throughout stroke.
• Automatically sets input span to match valve travel.
• Compact size to allow installation in limited space.
• Manual override to allow positioning of valve and preload.
• Spring return stem up operation.
• Direct mount to valves without separate linkage.
