Description
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 valves from 1/2" to 2" VB-7xxx and discontinued 1/2" to 1-1/4" VB-9xxx in chilled water, hot water and steam applications up to 366 °F (186 °C). 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 0-3 Vdc, 6-9 Vdc, 0-10 Vdc, 0-20 mAdc, 2-10 Vdc, or 4-20 mAdc. Control function direct/reverse action is jumper selectable
  • 105 lb force (467 newton) with 1/2" (13 mm) nominal linear stroke
  • Rugged polymer housings rated for up to NEMA 2/IP54
  • 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 operation
  • Direct mount to valves without separate linkage
  • Polymer housing rated for plenum use
