This Titan 700-158 potentiometer assembly is a direct replacement component that supersedes the original Titan 507973. It is designed for use on compatible Airless Sprayer, Performer, PowrLiner, ProMark II, and RentSpray equipment. It converts the operator's pressure setting into an electrical signal that controls the drive system, ensuring precise pressure regulation and consistent spray performance. Replacing a faulty or unresponsive potentiometer assembly restores accurate pressure control, prevents fluctuations, and maintains optimal spray quality.

The Titan 700-158 Potentiometer Assembly is a genuine replacement component that supersedes the original Titan 507973. It is designed for use on compatible Airless Sprayer, Performer, PowrLiner, ProMark II, and RentSpray equipment. This precision potentiometer converts the operator's pressure setting into an electrical signal that controls the drive system, enabling precise pressure regulation and consistent spray performance.
In electronically controlled spray systems, the potentiometer is the primary interface between the operator and the machine's pressure control. It allows for smooth, stepless adjustment of fluid pressure to match application requirements. Over time, potentiometers can wear due to repeated use, develop dead spots, or fail due to electrical stress or contamination. A faulty potentiometer can cause erratic pressure control, inability to adjust pressure, or complete loss of control. Replacing a failed potentiometer assembly with this direct replacement (superseding 507973) restores accurate pressure adjustment, ensures consistent spray quality, and maintains reliable equipment operation.
| Pressure adjustment | Converts knob position into electrical signal for pressure control |
|---|---|
| Operator interface | Provides smooth, precise control of fluid pressure |
| System feedback | Sends setpoint signal to the drive control system |
| Erratic pressure | Pressure jumps or fluctuates without adjustment |
|---|---|
| Dead spots | No response when turning knob through certain positions |
| No response | Pressure does not change when knob is turned |
| Physical damage | Cracked housing, loose shaft, or broken terminals |

When replacing the potentiometer assembly, these associated components are often inspected or replaced to ensure a complete repair.
Check knob for cracks or loose fit; replace if damaged.
Inspect wires and terminals for corrosion or damage; repair as needed.
Verify that the control board receives the signal correctly; test if issues persist.
