Titan part 0509781 is a return spring designed to provide restoring force for a valve, lever, or trigger mechanism on compatible SprayTech LCX 130, LC 1600, and PowrLiner 6950, 4950, 2850, and 550 stripers. This spring ensures that the component returns to its default position after actuation, enabling consistent operation and operator safety. Replacing a broken, weakened, or missing return spring restores proper reset action, prevents sticking, and ensures reliable machine control.

The Titan 0509781 Return Spring is an OEM extension or compression spring used to return a control lever, valve stem, or trigger mechanism to its home position after actuation. It is precision‑wound from durable spring steel to maintain consistent tension over thousands of cycles.
Return springs can fatigue, take a permanent set, or break from repeated use. A weak or broken spring may cause a valve to stick open, a lever to feel floppy, or the sprayer to fail to reset correctly. Replacing with genuine Titan 0509781 restores positive return action, improves operator feel, and ensures safe, predictable machine response.

When replacing a return spring, consider inspecting or replacing these associated components.
Inspect for wear or sticking; replace if the valve does not move freely.
If the spring is part of a valve assembly, replace seals at the same time to prevent leaks.
Check for cracks or bending that could affect spring alignment.
