APOLLO Pressure Relief Valve & Grease Nipple for Asphalt Paver S1800-3

This product listing features two essential, genuine APOLLO maintenance components designed for the track drive system of the S1800-3 asphalt paver. The package includes the Pressure Relief Valve and the Track Tension Grease Nipple, identified by part number 2306184. Together, they are critical for the proper function, longevity, and safe operation of the paver's undercarriage.

The APOLLO Pressure Relief Valve is a key safety and protection device within the track tensioning circuit. Asphalt pavers operate under extreme conditions with significant loads and constant vibration. The hydraulic system that adjusts track tension can experience pressure spikes due to thermal expansion, impacts, or operational stress. This relief valve is precision-calibrated to automatically open and divert excess hydraulic fluid when pressure exceeds a safe threshold. This action prevents catastrophic damage to expensive components like hydraulic cylinders, hoses, and pumps. By bleeding off excess pressure, it safeguards the entire track tensioning system from failure, which could lead to track derailment or loss of machine mobility on the job site—a scenario that causes costly downtime and project delays.

The Track Tension Grease Nipple (Zerk Fitting) is a fundamental yet vital part of routine paver maintenance. This nipple serves as the access point for lubricating the track tensioning cylinder and pivot points. Regular greasing is mandatory to combat the severe wear caused by continuous exposure to asphalt debris, dust, moisture, and grit. This fitting allows maintenance personnel to efficiently inject high-quality grease, which forms a protective seal, displaces contaminants, and minimizes metal-on-metal friction. Proper lubrication ensures the tensioning mechanism operates smoothly, allowing for precise track adjustment and preventing seizing or corrosion that could lock the system.

Using genuine APOLLO components, such as those specified by part number 2306184 for the S1800-3 model, guarantees exact compatibility and reliable performance. These parts are engineered to the original equipment manufacturer's specifications for dimensions, pressure ratings, and material durability. Installing this matched set ensures the track tensioning system operates as designed—with protected hydraulics and proper lubrication. This translates directly into reduced unplanned downtime, lower long-term repair costs, and maximized machine availability for your paving projects. For paver owners and fleet managers, this combination represents a proactive investment in machine reliability, protecting one of the paver's most critical and stress-prone systems.
