Multiquip 11810A3501 PCV Valve

The Multiquip 11810A3501 PCV Valve is a genuine OEM component designed for C30HDNI, C30HDNI Precision, C30HDN, and C30HDNI Zenith Mayco concrete pump models. As a direct OEM replacement, this valve meets the original design specifications set for these machines, ensuring correct crankcase ventilation performance without improvisation or guesswork. Sourced directly through Multiquip's authorized parts network, the 11810A3501 is the correct specification part for these C30 series concrete pumps.

Key Features

• Genuine OEM Crankcase Ventilation Control — Manufactured to the exact flow and pressure specs required by the C30 series engine, not a generic valve adapted to fit.
• Direct OEM Replacement — Installs into the existing PCV port on compatible C30 series concrete pumps with no adaptation needed to the valve cover or hose fittings.
• Broad C30 Series Coverage — Confirmed fitment across C30HDNI, C30HDNI Precision, C30HDN, and C30HDNI Zenith Mayco concrete pump variants.
• Protects Engine Internals — A properly functioning PCV valve prevents crankcase pressure buildup that can force oil past seals and into the intake, keeping the engine running cleanly under sustained pumping loads.
• Emissions and Engine Health Compliance — A functioning PCV valve is essential to proper closed-loop crankcase ventilation; a failed unit can cause rough running, increased oil consumption, and failed emissions checks on regulated jobsites.

The PCV (Positive Crankcase Ventilation) valve regulates the flow of blow-by gases from the engine crankcase back into the intake system, where they are burned off rather than vented to the atmosphere. This controlled ventilation prevents pressure from building up inside the crankcase, which would otherwise push past gaskets and seals and contaminate engine oil. When the PCV valve sticks open or closed, the engine can run rough, consume excess oil, or suffer accelerated internal wear — making timely replacement a straightforward way to protect a significant equipment investment.
