FS10 Burner Servo Motor

The FS10 is a servo motor Zhongli Weiye stocks as a compatible spare, used to position the gas valve or air damper on burners so combustion tracks the control box's setpoint. Where the GT31 is sized for damper modulation, the FS10 is the compatible option plants hold for the same actuator family when the original is a different form factor, and we verify shaft, torque and feedback against the existing actuator. It is not a branded original; it is the local, cross-checked spare that restores modulation quickly when an actuator fails mid-season. The FS10 is the compatible standby for actuators whose original is an FS-series form factor, so a mid-season actuator failure does not mean an OEM lead-time wait. Like the GT31 it positions the air damper or gas valve and reports feedback, but it is sized and drilled for the FS form factor we verify shaft, torque and signal against the existing actuator before supply so it drops in. On the bench the FS10 delivers 6 Nm of torque across a 90-degree stroke and reads position through a built-in potentiometer, so it is sized for butterfly and ball valves on the gas train where a small sealed body must hold a precise modulation angle. It fits DN20 to DN50 valve shafts.

Why buyers choose it

• The FS10 is a servo motor stocked by Zhongli Weiye as a compatible spare, driving a burner damper or modulating valve to the control box's commanded position.
• Fitment: Mounted on the air damper or gas valve to modulate combustion air and fuel.
