Western 49229K-1 – 4-Way Hydraulic Valve with Nut

The genuine Western 49229K-1 4-Way Hydraulic Valve serves as a critical directional fluid control component within the plow manifold block. Also stamped as industry reference DASV08-40 and widely identified as Cartridge 40, this factory-original valve governs the precise passage of high-pressure hydraulic oil to individual cylinders. By executing mechanical shift sequences inside the manifold, this 4-way cartridge enables the fundamental structural movements of your plow setup, alternating fluid distribution to command clean lifting, lowering, and left-or-right angling.

This original manufacturer replacement valve features a precision-machined cartridge body engineered to seat natively within the valve manifold. Because it is a factory-authorized component, it establishes an airtight internal seal that prevents internal fluid bypass, a common cause of slow blade creep, sluggish angling response, or sudden dropping under load. The kit comes complete with the specific heavy-duty mounting jam nut required to secure the valve firmly into the manifold housing, ensuring a stable seat that eliminates high-frequency mechanical vibration and blocks external fluid weeping.

For commercial operators and fleet service managers, installing original factory cartridges preserves the performance specifications of the hydraulic system and prevents electrical coil damage. This versatile valve interfaces seamlessly across a broad range of legacy and modern equipment, including older Unimount straight-blade Isarmatic solenoid pump networks and newer UltraMount and UltraMount 2 straight-blade systems. Replacing a jammed, contaminated, or scarred cartridge valve during standard seasonal maintenance ensures your equipment responds instantly to in-cab controller commands during heavy winter storms.

Benefits of the Western 49229K-1 Valve

• Genuine OEM Component: Manufactured to original factory tolerances to ensure absolute compatibility with Western and Fisher straight-blade hydraulic systems.

• Eliminds Fluid Internal Creep: Precision internal tolerances stop internal hydraulic oil bypass, maintaining exact blade height and angling positions.

• Includes Jam Fastener: Ships with the factory-matched mounting nut to provide a stable, vibration-resistant installation in the shop.

• Broad Fleet Compatibility: Operates perfectly inside early UniMount Isarmatic pumps and continues through modern UltraMount 2 straight-blade valve manifolds.

• Restores System Timing: Eliminates cylinder drag and sluggish command delays, translating operator controller inputs into immediate mechanical action.
