Heinzmann - Model RPLV-2S -Rail Pressure Limiting Valve

Pressure is limited, then reduced to the holding pressure (“limp home”). 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 limp- home 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.
