Multiquip 01321100 Oil Relief Valve Assembly

The Multiquip 01321100 Oil Relief Valve Assembly is a genuine OEM component designed for the MVH508DZ reversible plate compactor. Sourced directly from Multiquip, this assembly ensures an exact fit and correct pressure calibration for the hydraulic system on MVH508DZ equipment. Keeping this component in proper working order is essential to protecting the compactor's internal hydraulic circuit from pressure spikes that can damage downstream components. DHS Equipment stocks this genuine OEM part so you can get your machine back to work without compromise.

Key Features

• Genuine OEM Pressure Calibration — Factory-set relief pressure rating specific to the MVH508DZ hydraulic circuit, ensuring the valve opens and closes at the correct threshold rather than an approximated aftermarket value.
• Direct Assembly Replacement — Supplied as a complete assembly that installs directly into the existing valve port without additional adapters or modifications to fittings.
• Confirmed Fitment for MVH508DZ — Engineered specifically for the Multiquip MVH508DZ reversible plate compactor; verify your model code before ordering.
• Hydraulic System Protection — A correctly functioning relief valve prevents over-pressurization that can blow seals, damage the hydraulic pump, or cause loss of plate reversing function.
• Fuel and Fluid System Safety — A failed or sticking relief valve can cause uncontrolled pressure buildup in the hydraulic circuit, creating unsafe operating conditions on compaction equipment.

The oil relief valve assembly regulates hydraulic pressure within the compactor's hydraulic circuit by opening at a preset pressure limit and diverting fluid back to the reservoir when that limit is reached. This prevents excessive pressure from building up and damaging seals, lines, and the hydraulic pump. When the relief valve wears out or sticks, operators may notice erratic plate reversal behavior, loss of compaction force, or hydraulic fluid leaks — all signs that the assembly needs immediate replacement.
