Proportional Actuator w/ 4-20 mAdc Control Signal (24V)

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.FeaturesTwo 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 Five year warranty
