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.
