The Multiquip 04038500 Oil Restrictor Valve Assembly is a genuine OEM component designed for a range of Multiquip equipment including the MVH502DSB and MVH502DSB2 reversible plate compactors, the MDR-9D power trowel, and the MQ41TDH trash pump. Sourced directly from Multiquip, this part matches the original specification exactly, ensuring a seamless installation with no guesswork. Confirmed fitment across the MVH502DSB, MVH502DSB2, MDR-9D, and MQ41TDH means you can order with confidence knowing this is the correct part for your machine. Keep your equipment running at the right oil pressure by replacing worn or failed components with this factory-original assembly.
Key Features
- Genuine OEM Precision Flow Control — manufactured to the exact flow restriction tolerances of the original part, maintaining correct oil pressure throughout the lubrication circuit.
- Direct Drop-In Installation — matches the original mounting configuration and port sizing for a straightforward swap with no reworking of existing fittings or lines.
- Broad Confirmed Fitment — compatible with MVH502DSB, MVH502DSB2, MDR-9D, and MQ41TDH, covering reversible plate compactors, power trowels, and trash pumps in the Multiquip lineup.
- Protects Engine and Hydraulic Components — a correctly functioning restrictor valve regulates oil flow to downstream components; a failed or worn valve can starve critical surfaces of lubrication, accelerating wear across the system.
- Fuel System and Lubrication Safety — maintaining proper oil restriction is essential to preventing over-pressurization or oil starvation events that can cause sudden mechanical failure during operation.
The oil restrictor valve assembly controls the rate at which oil flows through a specific passage in the lubrication or hydraulic circuit, acting as a calibrated orifice to maintain consistent pressure and flow to downstream components. Without proper restriction, oil can bypass critical areas too quickly, leading to pressure drops, inadequate lubrication, and accelerated wear on bearings, seals, and moving parts. When this assembly fails — whether through blockage, cracking, or internal wear — the result is often erratic machine behavior, overheating, or premature component damage, making timely replacement essential to keeping the equipment operating safely and efficiently.
