Our company today announced the launch of the APOLLO S1800-3i Travel Speed Potentiometer, a precision control for asphalt paver spare parts. Mounted on the operator console, the potentiometer regulates the proportional solenoid valve of the travel pump, giving smooth and accurate control of track motor speed during paving.
The potentiometer works as a precision multi-turn device. As the operator turns the knob, it outputs a continuous voltage signal that the control system uses to set the opening of the travel pump solenoid valve. The result is smooth speed adjustment from zero to maximum, helping crews hold a steady paving speed and produce a consistent asphalt mat.
