Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact tolerances for the unloader valve circuit, ensuring consistent pressure regulation and correct hydraulic response on the MQC-180.
- Direct-Fit Replacement — Engineered to install in the same position as the original valve with no modification to surrounding hydraulic lines or fittings.
- MQC-180 Specific — Confirmed fitment for the Multiquip MQC-180 concrete pump; verify your model before ordering to ensure compatibility.
- Pressure System Integrity — A properly functioning unloader valve maintains correct system pressure during pump operation, protecting downstream components from overload and keeping output consistent.
- Hydraulic Circuit Reliability — Using the correct OEM valve prevents pressure bleed-off, erratic pump behavior, and premature wear on seals and valves throughout the system.
The unloader valve on a concrete pump regulates hydraulic pressure within the system by diverting flow when pressure reaches a set threshold, preventing overloading of the pump circuit. On the MQC-180, this valve plays a critical role in maintaining smooth, controlled concrete delivery — a worn or failed unloader valve can cause inconsistent output pressure, system overheating, or complete loss of pumping performance. Replacing it with the correct OEM component, Multiquip 170404310, ensures the pressure circuit operates within its designed parameters.
