Compatibility Table
Precision regulator spring restores proper pressure control and consistent spray performance.
Titan Fluid Regulator Component
Titan 0533556 is an OEM replacement spring used in the high-pressure fluid regulator assembly of the AirCoat 423 airless spray system.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan regulator spring that provides the calibrated force for the high-pressure fluid regulator assembly in the AirCoat 423 system. |
| Function | Provides the counter-force against the regulator diaphragm, allowing the adjustment mechanism to set the desired fluid outlet pressure. When the regulator knob is turned, it compresses or decompresses this spring, changing the force applied to the diaphragm and thereby controlling system pressure. A weak, broken, or fatigued regulator spring leads to unstable pressure, difficulty adjusting pressure, or complete loss of regulation. |
| Industrial Applications | Professional sprayer repair, regulator rebuilding, pressure control system maintenance, and preventive maintenance of AirCoat 423 spray systems. |
| Compatible Titan Machines | AirCoat 423 Airless Spray System. |
| Accurate Part Number | 0533556 Spring Regulator. |
| Compatible Parts & Assemblies | High-pressure fluid regulator assembly, regulator housing (0533534), regulator cap (0533555), and related pressure control components. |
| Related Parts Commonly Serviced Together | Regulator housing, regulator cap, O-rings, copper gaskets, and pressure gauge components. |
| Common Problems Solved | Pressure instability, difficulty adjusting pressure, inability to maintain consistent fluid pressure, and erratic spray performance due to a worn or fatigued regulator spring. |
| Use with Coating Systems | Supports the AirCoat 423 system used by painting contractors, wood finishers, and industrial finishing professionals. The system delivers up to 2670 psi with a 23:1 pump ratio. |
| OEM & Brand Information | Genuine Titan OEM component designed for correct fitment in the AirCoat 423 high-pressure fluid regulator assembly. Use of genuine Titan replacement springs ensures accurate pressure control and system safety. |
| Commercial Benefits | Restores accurate pressure regulation, ensures consistent fluid delivery, maintains stable spray performance, and extends equipment service life. |
The 0533556 Spring Regulator is an internal component of the high-pressure fluid regulator assembly used on the AirCoat 423 airless spray system. It provides the counter-force against the regulator diaphragm, allowing the adjustment knob to set the desired fluid outlet pressure. A weak, broken, or fatigued regulator spring leads to unstable pressure, difficulty adjusting pressure, or complete loss of regulation. If you experience pressure surging, inability to maintain a consistent set pressure, or erratic spray performance, inspect the regulator spring for signs of fatigue or breakage. When servicing the regulator, always use genuine Titan replacement springs to ensure accurate pressure control and proper system operation.
