TECHNICAL DATA, M1500A
TAC Forta M1500A
Forta M1500A series Non-Spring Return linear actuators are
designed to mount directly on to VB-72xx two way globe
valve with a AV-811
linkage kit
(ordered separately) or VB-
8xxx two and three way globe valves and
VB-9313-0-5-xx
three way globe valves with a AV-812 valve linkage kit (ordered
separately).
Applications include chilled or hot water and steam.
Field selectable input signals include reverse and direct
acting, Floating or Proportional 0-10, 2-10 vdc or 4-20 ma with
500 Ohm resistor (supplied) plus proportional sequencing
input signal ranges.
FEATURES
- Floating configuration controlled by a SPDT floating
controllers
- Proportional configuration 0-10, 2-10 vdc or 4-20 ma with
the addition of a 500 ohm resistor included
Direct/Reverse action switch selectable
- 337lbf (1500N) linear force
- 24 Vac powered
- Die-cast housing with plenum rated plastic cover for NEMA
2 (IP54) applications
- Manual override to allow positioning of valve
- Electronic valve sequencing and Electronic flow curve
(equal percentage or Linear) selection.
- Torque overload protection throughout stroke
- Easy “One Touch” input signal/stroke calibration
