t.a.c. Forta M400A Instructions Manual

Forta M400A / M800A series Non-Spring Return linear actuators
are design to mount directly onto globe valves with linkage kits
ordered separately, M400A requires AV-811 linkage kit for
mounting to VB-7xxx valves and the M800A requires AV-811
linkage kit for mounting to VB-7xxx or AV-812 for mounting to
Applications include chilled or hot
VB-9313-0-5-xx valves.
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.
