The Royal Enfield Genuine Pressure Control Valve (Part No. RAD00002/A) is a factory-original emission control component designed specifically for Unit Construction Engine (UCE) BS4 models. This valve is a core element of the motorcycle’s Evaporative Emission Control (EVAP) system, regulating the flow of volatile fuel vapors from the petrol tank into the charcoal canister and intake manifold.
As shown on the official packaging label in image_3421a2.png and the product profile in image_342468.png, this precision check-valve operates based on engine vacuum pressure. It ensures that dangerous fuel vapors are stored and purged correctly during combustion rather than escaping into the atmosphere. Utilizing a genuine RAD00002/A valve maintains the exact factory pressure thresholds required to keep your engine idling smoothly and running efficiently without creating vacuum locks inside the fuel tank.
