The Role of Diverter Valves in Hydraulic Systems
Diverter valves, also known as splitter valves, are essential components in hydraulic systems when multiple functions must be controlled from a single circuit. These valves redirect hydraulic flow from one path to another, allowing operators to switch between attachments or auxiliary functions without installing a separate control valve for each. In electric diverter valves, solenoids trigger the redirection, making them ideal for retrofitting older machines with modern capabilities.
In the context of backhoe loaders like the Case 580 Super M, diverter valves are often used to repurpose existing controls—such as the extendahoe foot pedal—to operate auxiliary hydraulic attachments like compactors, hammers, or augers.
Case 580 Super M Development and Legacy
The Case 580 series has been a cornerstone of the backhoe loader market since its inception in the 1960s. The Super M variant, introduced in the early 2000s, featured upgraded hydraulics, improved operator ergonomics, and a more powerful engine. Manufactured by Case Construction Equipment, a division of CNH Industrial, the 580 Super M became one of the most widely sold backhoes in North America, with tens of thousands of units deployed across construction, agriculture, and utility sectors.
Case’s legacy dates back to 1842, when Jerome Increase Case founded the Racine Threshing Machine Works. Over the decades, Case evolved into a global leader in heavy equipment, known for its rugged designs and operator-friendly innovations.
Mounting Location and Plumbing Strategy
When installing an electric diverter valve on a Case 580 Super M, the mounting location and plumbing sequence are critical for performance and reliability. The boom of the machine typically houses two fixed steel hydraulic lines that transition into flexible hoses near the dipper arm. The diverter valve should be installed after the steel lines and before the hoses to simplify maintenance and reduce vibration stress.
Key considerations include:
The Case 580 Super M often comes equipped with one-way auxiliary hydraulics, suitable for tools like hydraulic hammers that require pressure in one direction and rely on gravity or internal rebound for return. However, attachments like augers or grapples require two-way flow for full functionality.
Installing a diverter valve enables the conversion of existing one-way circuits into switchable two-way systems. This expands the machine’s versatility and reduces the need for external hydraulic kits.
Terminology and Component Notes
A contractor in Wisconsin retrofitted his 580 Super M with a diverter valve from BIC to power a compactor. Initially, the setup appeared cobbled together, but with careful hose routing and bracket fabrication, the system became both functional and clean. He used the extendahoe pedal to toggle the valve, allowing seamless switching between digging and compacting.
In another case, a utility crew in Alberta installed a diverter valve to operate a hydraulic auger. They mounted the valve on a custom steel plate welded to the boom, with quick-connect fittings for fast attachment changes. The system reduced downtime and improved trenching efficiency.
Maintenance and Troubleshooting Tips
To ensure long-term reliability of the diverter valve system:
Operators planning to add diverter valves to older machines should consider:
Mounting a diverter valve on a Case 580 Super M is a practical upgrade that enhances hydraulic flexibility and attachment compatibility. With thoughtful planning, precise installation, and regular maintenance, operators can transform their backhoe into a multi-function tool carrier. Whether powering a compactor, hammer, or auger, the diverter valve becomes a gateway to expanded capability—bridging the gap between legacy design and modern demands.

The boom of the machine typically houses two fixed steel hydraulic lines that transition into flexible hoses near the dipper arm. The diverter valve should be installed after the steel lines and before the hoses to simplify maintenance and reduce vibration stress.
Key considerations include:
- Mounting Surface Stability
Choose a rigid, vibration-resistant location near the transition point between steel and hose. This minimizes movement and protects the valve body.
- Hose Routing and Clearance
Ensure that hydraulic hoses connected to the diverter valve are properly clamped and routed to avoid abrasion or kinking during boom articulation.
- Electrical Supply and Protection
The valve requires a 12V power source, typically drawn from the machine’s accessory circuit. Use weatherproof connectors and fuse protection to prevent shorts or corrosion.
- Control Integration
Repurposing the extendahoe foot pedal as the activation switch for the diverter valve is a practical solution. This allows the operator to toggle auxiliary hydraulics without adding new controls.

Terminology and Component Notes
- Extendahoe
A telescoping dipper arm extension that increases reach. The foot pedal controlling this function can be repurposed for auxiliary hydraulic activation.
- Solenoid Valve
An electrically actuated valve that redirects hydraulic flow when energized. Common in diverter applications.
- Auxiliary Hydraulics
Additional hydraulic circuits used to power attachments beyond the standard loader and backhoe functions.
- Hydraulic Hammer
A percussion tool powered by hydraulic pressure, used for breaking concrete or rock.
- Compactor Wheel
A rotating attachment used to compress soil or backfill material in trenches.

Maintenance and Troubleshooting Tips
To ensure long-term reliability of the diverter valve system:
- Inspect Electrical Connections Monthly
Check for corrosion, loose terminals, and damaged insulation.
- Test Valve Function Before Each Shift
Activate the valve and verify flow direction using a pressure gauge or visual confirmation.
- Monitor Hose Wear and Replace as Needed
Hydraulic hoses near the boom are subject to flexing and abrasion. Use protective sleeves and replace worn hoses promptly.
- Clean Valve Body During Routine Service
Dirt and debris can accumulate around the valve, especially in dusty environments. Use compressed air and a soft brush to clean.
Operators planning to add diverter valves to older machines should consider:
- Valve Sizing
Match the valve’s flow rating to the machine’s hydraulic output. Undersized valves can restrict flow and overheat.
- Bracket Fabrication
Use steel plates with gussets for strength. Avoid mounting on thin sheet metal or plastic surfaces.
- Quick-Connect Couplers
Install couplers rated for high pressure and frequent use. This simplifies attachment changes and reduces leaks.
- Documentation and Labeling
Label hoses and connectors to prevent confusion during maintenance. Keep wiring diagrams and valve specs in the cab.
