⚙️ Key Features

• Genuine Volvo Penta calibrated pressure-control component
• Original part number 21148935
• Controls or limits pressure within the assigned system circuit
• Factory-set internal spring / valve characteristics
• Not interchangeable with visually similar governors or regulators
• Engine type: Application-specific Volvo Penta marine or industrial engine system

🔌 Function

Maintains the assigned circuit pressure within its calibrated operating range by opening, closing or bypassing flow as required.

⚠️ Common Signs of Failure

• Pressure remains above or below specification
• Erratic pressure or repeated warning alarms
• Valve sticking from contamination or corrosion
• Leakage at the regulator body or connection
• Poor system response after temperature or load changes

🛠️ Service Notes

• Record the position and setting of every linkage, stop and adjuster before the old governor comes off, so the new one can be set up the same way
• Work clean and keep the fuel system covered while the governor is off — dirt entering here does expensive damage downstream
• Fit new gaskets, O-rings and seals on all joint faces, and use new locking devices on any linkage fasteners
• Set linkage travel, stops and speed settings only to the values in the workshop manual for your engine; a governor set outside those limits can let the engine overspeed
• Have the engine run up and the idle, maximum speed and shutdown behaviour checked by someone equipped to do it before the boat goes back into service

📦 Condition
