Replacement potentiometer knob kit designed for precise manual control in Graco spray equipment, ensuring smooth adjustment of system output settings.
The Graco MTA837 KIT, KNOB, POTENTIOMETER is used in professional Graco spray systems featuring electronic pressure or speed control interfaces.
*Compatibility confirmed from Graco electrical enclosure parts breakdowns where MTA837 is listed as a potentiometer knob assembly component.
The Graco MTA837 KIT, KNOB, POTENTIOMETER is an OEM replacement control knob designed for use in Graco spray equipment control systems. It is mounted on the potentiometer shaft and allows operators to manually adjust key machine settings such as pressure, flow rate, or motor speed depending on the system configuration.
This component is part of the electrical control interface and is typically paired with a 5K potentiometer assembly. It provides precise tactile control, ensuring accurate adjustment of spray output in professional coating applications.
In Graco system documentation, the MTA837 is listed as a dedicated knob used within control enclosures alongside other critical electrical components such as VFD modules, harnesses, and switches.
The MTA837 does not function independently; it works as a mechanical interface for the potentiometer system. When rotated, it adjusts the electrical resistance in the potentiometer, which then signals the control board to regulate machine output.
This makes it a small but essential part of maintaining consistent spray performance, especially in high-demand professional coating and line-marking applications.
