The Multiquip 507774 Relief Valve Rdh103F10-070 Vr36H is a genuine OEM hydraulic relief valve designed for AR-series asphalt ride-on rollers including the AR13H, AR13HA, AR13HAR, AR13HC, AR13D, and AR14H. As a direct OEM replacement sourced through Multiquip's authorized parts network, 507774 meets the original engineering specification for your machine's hydraulic system. DHS Equipment stocks this part to keep your roller running at full capacity with the correct pressure control components installed.
Key Features
- Genuine OEM Hydraulic Specification — Manufactured to the exact pressure rating and porting configuration required by the AR-series roller hydraulic circuit, ensuring correct system response under load.
- Direct-Install Replacement — Matches the original valve body dimensions and port threading of the 507774 application, dropping into the existing hydraulic block without modification.
- Broad AR-Series Compatibility — Confirmed fitment across AR13H, AR13HA, AR13HAR, AR13HC, AR13D, and AR14H ride-on asphalt roller models.
- Hydraulic System Pressure Control — Maintains safe operating pressure within the roller's hydraulic circuit; a worn or failed relief valve can cause erratic drum drive behavior, overheating, or loss of compaction force.
- Authorized OEM Part — Supplied as a genuine Multiquip component, so you can be confident the part installed in your machine meets the original design intent without compromise.
A hydraulic relief valve regulates maximum pressure within a hydraulic circuit by diverting excess fluid back to the reservoir when pressure exceeds a set threshold. On an AR-series asphalt ride-on roller, this valve protects the drum drive system and hydraulic components from pressure spikes that can occur during operation on grades or when the machine encounters resistance. When a relief valve fails or sticks open, the system loses the ability to maintain working pressure, which can result in sluggish drum drive, overheating of hydraulic fluid, or accelerated wear on pumps and motors.
