The Husqvarna 578243306 Valve Assembly is a genuine OEM component designed for the K540i, K770, K970, and K1PACE power cutters. As a direct Husqvarna OEM part, it meets the exact design and material specifications of the original, ensuring a correct, reliable fit within the fuel or fluid circuit of your machine. This assembly is compatible across the K-series power cutter lineup, making it a straightforward replacement when the original valve shows wear or failure. DHS Equipment supplies this part to help keep your equipment running at full capability on the job.
Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact tolerances and material specifications, ensuring the valve seats, seals, and cycles precisely as the original did from the factory.
- Direct Assembly Replacement — engineered to install in the same location and orientation as the original valve assembly, with no rework or modification to surrounding components.
- Broad K-Series Compatibility — fits the K540i, K770, K970, and K1PACE power cutters, covering both battery-electric and petrol models in the K-series range.
- Restored Flow Control — a properly functioning valve assembly maintains correct fluid or fuel routing through the system; a degraded valve can cause erratic operation, hard starting, or loss of cutting performance.
- Verified Part Number — cross-reference 578243306 against your machine's parts diagram to confirm the correct assembly before installation.
The valve assembly controls the flow of fuel or fluid through a critical circuit within the power cutter, regulating pressure and direction to keep the machine operating consistently under load. When the valve wears, sticks, or fails, the machine may exhibit rough running, inconsistent throttle response, or a complete loss of function in the affected system. Replacing the valve assembly with a genuine OEM unit restores proper flow regulation and brings the machine back to its designed operating condition.
