MAN Common Rail Pressure Limiting Valve 51103040120

MAN Common Rail Pressure Limiting Valve (PLV) – OE 51.10304.0120

Protect your high-pressure fuel circuit with our premium Pressure Limiting Valve. Specifically engineered for MAN heavy-duty engines, this valve acts as the primary safety mechanism for the fuel rail. It is designed to release extreme pressure spikes, preventing damage to expensive injectors and the high-pressure pump.

As a specialist manufacturer, we utilize hardened steel and high-tolerance internal springs to ensure the valve opens at the exact bar threshold required by MAN technical specifications and reseals perfectly to maintain engine uptime.

OE Reference & Identification

This part is a direct-fit replacement for the following original equipment reference:

• MAN: 51.10304.0120 / 51103040120
