Replacement Spring for Airless Sprayer Pressure Control Valves
The 800-926 Spring is a precision‑engineered component used in the pressure control or unloader valve assembly of many airless paint sprayers. It applies the correct force to regulate the valve’s switching point, ensuring the sprayer builds and maintains proper pressure while protecting the pump from overload.
A weak, fatigued, or broken spring can cause erratic pressure, failure to build pressure, or the sprayer to cycle continuously without spraying. Replacing a worn spring with this genuine part restores accurate pressure regulation and reliable operation.
What it does and when to replace it
| Pressure regulation | Provides the correct force to open/close the unloader valve at the set pressure |
|---|---|
| Cycle control | Ensures the pump cycles on and off at the proper pressure differential |
| System protection | Prevents the pump from dead‑heading when the gun is closed |
| Erratic pressure | Pressure surges or fluctuates while spraying or when gun is triggered |
|---|---|
| Failure to build pressure | Sprayer runs but never reaches full pressure, or cycles constantly |
| Motor stalling | Motor fails to kick out when gun is closed, or stalls under load |
| Visible damage | Spring is broken, deformed, or shows signs of fatigue/rust |

Related parts commonly serviced together
Pressure control issues often involve multiple components. When replacing the spring, inspect these related parts.
Worn seats or pistons can cause pressure loss even with a new spring.
Deteriorated o‑rings can lead to internal leakage and inconsistent pressure.
Damaged threads or binding can prevent proper spring tension adjustment.
