Description
Forta M400A (VB) / M800A (VB) /M1500A (VB) series NonSpring Return linear actuators are available in two styles, U-Bolt
Mount style, mounts to Schneider Electric globe valves with AV-
811 linkage kits for mounting to VB-7xxx valves or AV-812 for
mounting to VB-8xxx, or VB-9313-0-5-xx valves. Screw Mount
style, screws directly to the bonnet nut on VB-7xxx valves (no
adapter required).
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.
