Western 49138K-5 – RELIEF VALVE KIT – 2 SETS

Commercial snow removal subjects plow manifolds to severe hydraulic shocks. Therefore, operators install the Western 49138K-5 Relief Valve kit to safeguard vital internal system components. Specifically, these pressure relief mechanisms exhaust fluid when hitting hidden curbs or frozen hazards. Consequently, you protect the manifold block from cracking under sudden, extreme impact loads. Because delayed relief actions cause expensive pump blowouts, replacing worn valves guarantees continuous system safety.

Furthermore, this dual-set kit provides a complete overhaul for both angling circuits simultaneously. Due to tight factory calibrations, genuine Western components match exact original equipment tolerances perfectly. Fleet mechanics install the new cartridge assemblies directly into the FloStat block during standard annual checkups. As a result, the plow blade maintains correct relief settings during heavy containment runs. Ultimately, regular maintenance preserves expensive fleet assets and limits mid-storm breakdown costs.

Benefits of the 49138K-5 Relief Valve Kit

• Prevents catastrophic manifold block cracking by exhausting localized high-pressure fluid spikes instantly.

• Restores strict factory pressure relief thresholds to maintain stable side-to-side blade angling stability.

• Includes two complete valve replacement sets to overhaul both hydraulic cushion circuits together.

• Resists internal fluid contamination and structural binding through hardened, precision-machined steel components.

• Fits standard Western FloStat valve manifolds perfectly to simplify routine pre-season shop service.
