Multiquip EE42147 Proportional Relief Valve with Body 3000 PSI

The Multiquip EE42147 Proportional Relief Valve with Body 3000 PSI is a genuine OEM hydraulic control component designed for Multiquip studio and diesel-powered generator models including SG1400C3-55748, SG1400C4F, and SG1600C4F. As a direct OEM replacement, EE42147 is built to the exact pressure rating and dimensional tolerances required by these generator systems. Sourced directly through Multiquip's authorized parts network, this valve assembly ships as a complete unit with body included, making it a straightforward service replacement. If you need to confirm fitment for your specific unit, DHS Equipment's team is available to verify compatibility before you order.

Key Features

• Rated to 3000 PSI: Factory-rated pressure specification ensures the valve operates within the precise hydraulic pressure range required by the generator's control circuit — not an approximation.
• Complete Assembly with Body: Supplied as a full valve-and-body assembly, so the entire functional unit is replaced in a single service step without sourcing separate components.
• Genuine OEM Component: Manufactured to Multiquip's original design spec, ensuring correct proportional response characteristics that aftermarket substitutes may not replicate.
• Confirmed Generator Fitment: Verified for SG1400C3-55748, SG1400C4F, and SG1600C4F studio and diesel-powered generator models — consult DHS Equipment to confirm your serial range.
• Hydraulic Circuit Integrity: A correctly functioning proportional relief valve maintains stable hydraulic pressure regulation across the generator's control system; a failed or out-of-spec valve can cause erratic system behavior or pressure faults.

A proportional relief valve regulates hydraulic pressure within a system by opening progressively in response to rising pressure, allowing fluid to bypass rather than letting pressure build to a damaging level. In generator applications, this valve plays a critical role in maintaining consistent, controlled hydraulic output across the machine's operating range. When the valve wears, sticks, or loses calibration, the system may experience pressure spikes, inconsistent output, or automatic fault conditions that take the unit offline.
