n LPG filler valve (Bayonet & ACME) is a precision-engineered refueling interface used in vehicle LPG systems to enable safe, standardized, and leak-controlled transfer of liquefied petroleum gas into onboard cylinders.
In Kenya’s growing autogas ecosystem—especially in Nairobi, Mombasa, Kisumu, and Kampala—vehicle operators are increasingly shifting from petrol to LPG due to lower fuel costs, improved combustion efficiency, and reduced emissions.

Proper system design and installation is critical, which is why most commercial and fleet operators rely on Megtraco Kenya LPG engineering solutions for safe autogas conversion and compliant gas system integration.
TECHNICAL INDUSTRY OVERVIEW
What is an LPG Filler Valve?
An LPG filler valve is a safety-controlled inlet device mounted on a vehicle’s LPG cylinder. It allows fuel transfer from a dispensing nozzle into the tank while preventing backflow, leakage, and overfilling.
Bayonet and ACME systems are internationally recognized standards used in autogas refueling infrastructure to ensure compatibility across fueling stations and vehicle fleets.
Why It Is Critical in Autogas Systems
Without a standardized filler valve, LPG refueling becomes unsafe and inconsistent. The valve ensures:
- Controlled LPG transfer during refueling
- Prevention of gas backflow
- Pressure stability inside the cylinder
- Compatibility with fueling station nozzles
- Safe disconnection after refueling
Proper installation is typically part of certified autogas conversion Kenya projects designed to meet regulatory and engineering standards.
INDUSTRIAL & AUTOMOTIVE APPLICATIONS
1. Private Vehicle Conversion Systems
Used in passenger cars converted from petrol to LPG for cost savings and emissions reduction.
2. Fleet Transport Operations
Taxi fleets and logistics operators in East Africa use LPG systems to reduce fuel expenses and improve operational margins.
3. Commercial Delivery Vehicles
Light trucks and vans rely on standardized filler valves for fast refueling cycles and reduced downtime.
4. Industrial Utility Vehicles
Forklifts and warehouse vehicles also depend on LPG systems using similar refueling interfaces for safe operation.
For large-scale deployments, operators often integrate industrial LPG equipment systems for compatibility across multiple vehicle types.
