Heinzmann - Model RPLV-1S -Rail Pressure Limiting Valve

Pressure is limited; only a temporary safety function is provided. The engine must be stopped. Primarily the Rail Pressure Limiting Valves (RPLV) are designed to protect common rail equipment against overpressure. Differing to RPLV-1S the 2S-version additionally offers the important limphome function. After opening due to overpressure RPLV-2S works as a rail pressure control valve and keeps up some holding pressure under any system conditions even without risk of overheating. This provides high reliability and ensures engine running.
