This spring is installed inside the following regulator valves:
What This Spring Does
The red spring controls the internal resistance of the regulator valve, allowing the operator to fine‑tune solution pressure up to 400 psi. A weakened or corroded spring can cause pressure drift, inconsistent spray, or difficulty maintaining set pressure.
When to Replace
We recommend replacing this spring whenever servicing or rebuilding the 400 psi pressure regulator valve, especially if:
- Pressure fluctuates during use
- The regulator feels loose or overly stiff
- Pressure cannot be set accurately
- The valve has been stripped for cleaning or maintenance
For full regulator servicing, the Plunger Repair Kit is also available and includes the internal components most commonly replaced during a rebuild:
