🔧 Product Description
A genuine engine-brake control valve used on compatible Volvo D12-based installations. It controls the pneumatic or oil-actuated engine-brake circuit and must match the exact engine-brake configuration.
⚙️ Key Features
- Calibrated for the documented rated-speed or engine-control configuration
- Cross-referenced to Volvo 20508910/20564732 and Renault Group 7420913287/7424426572
- Maintains commanded speed as engine load changes
- Mechanical interfaces match the specified linkage and fuel-control travel
- Engine type, serial number, rated power and governed rpm are required for correct selection
- Final adjustment must follow the Volvo Penta governing procedure
- Inspect linkage freedom, return springs and fuel-system condition before replacement
- Engine type: Volvo Penta D12 inline-six industrial diesel
🔌 Function
Controls flow or pressure in the engine-brake or related control circuit.
⚠️ Common Signs of Failure
- The engine brake weak, slow to apply, or not working at all
- The brake staying partly applied, giving a rough idle and lost power
- Hissing or an audible leak from the valve when the brake is commanded
- A fault code raised against the engine-brake circuit
- On strip-down, a sticking spool, perished seals or a blocked control drilling
🛠️ Service Notes
- Supersedes 20450036
- Check the control supply and the wiring before condemning the valve - a low supply pressure gives identical symptoms
- Engine-brake configuration varies within the family, so confirm the valve against the engine number rather than by appearance
