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-
- 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
