Forta M400A (VB) / M800A (VB) /M1500A (VB) series Non-Spring
Return linear actuators are available in U-Bolt (Mx00A) and Screw
Mount (Mx00A-VB) style for Schneider Electric globe valves with
AV-821 linkage kits for mounting to VB-7000 valves. The Screw Mount
style screws directly to the bonnet nut on VB-7000 valves (no adapter
required). Applications include chilled or hot water and steam.
Benefits
• Field-selectable input signals include reverse and direct-acting,
Floating or Proportional plus proportional sequencing input signal
ranges.
• Floating configuration - controlled by a SPDT floating controller
• 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
• Linear force: 90 lbf (400N), 180 lbf (800N), 337 lbf (1500N)
• Die-cast housing with plenum-rated plastic cover for NEMA 2 (IP54
vertical mount only) applications
• Manual override to allow positioning of valve
• Electronic valve sequencing and electronic flow curve (equal per-
centage or Linear) selection.
• Torque overload protection throughout stroke
• Easy “One Touch” input signal/stroke calibration
