PowrLiner / Elite part 9994245 is a pressure spring designed to apply consistent force in pressure regulation or control mechanisms on compatible sprayer models. This precision spring maintains proper tension against valves or diaphragms to ensure accurate pressure control and reliable system operation. Replacing a worn, weakened, or damaged pressure spring restores proper pressure regulation and ensures consistent spraying performance.

The 9994245 Pressure Spring is a precision-engineered spring used in pressure regulation or control mechanisms on compatible PowrLiner and Elite sprayer models. It applies consistent force against valves, diaphragms, or pistons to establish and maintain proper operating pressure.
Pressure springs are critical components in regulating systems. They work against fluid pressure to control valve position, maintaining the set pressure by balancing spring force against hydraulic force. The spring must provide consistent, repeatable force over millions of cycles without taking a set or losing tension. Manufactured from high-quality spring steel, this spring is designed to maintain its characteristics throughout its service life.
Over time, pressure springs can weaken from fatigue, take a compression set, or corrode from environmental exposure. A worn or weakened spring can cause pressure fluctuations, inability to reach set pressure, or poor regulation. This can result in inconsistent spray patterns, material waste, and poor finish quality. Replacing a worn pressure spring restores proper force balance, ensuring accurate pressure control and consistent spraying performance.
| Force application | Applies consistent force to pressure-regulating elements |
|---|---|
| Pressure setting | Establishes the baseline for system operating pressure |
| Regulation | Works against fluid pressure to maintain set point |
| Pressure fluctuation | Pressure varies during operation, unable to maintain set point |
|---|---|
| Inability to reach pressure | System cannot achieve normal operating pressure |
| Visible fatigue | Spring appears distorted, sagging, or corroded |
| Missing spring | Spring lost, no pressure regulation |
