The Multiquip EM98224 is a genuine OEM Main Relief Valve designed for Mayco hydraulic-driven concrete pumps, including the LS40D, LS40TD, LS50TD, LS60TD, and LS600 series. As an authentic Multiquip OEM component, EM98224 is manufactured to the exact specification required by your pump's hydraulic system, ensuring consistent pressure regulation and safe operation. Verified fitment across the LS-series concrete pump line means you can order with confidence that this valve will install directly into your machine.
Key Features
- Hydraulic Pressure Integrity — Engineered to maintain precise system pressure thresholds specific to LS-series hydraulic concrete pump circuits, preventing over-pressurization at the hydraulic drive.
- Genuine OEM Component — Sourced directly from Multiquip, this valve matches the original pressure rating and port dimensions of the factory-installed unit for a direct, bolt-in installation.
- Broad LS-Series Compatibility — Confirmed fitment for LS40D, LS40TD, LS50TD, LS60TD, and LS600 Mayco concrete pump models from a single part number.
- Sustained Pumping Output — A correctly functioning relief valve keeps hydraulic pressure within operating range, supporting consistent concrete output volume and protecting the pump's hydraulic motor from damage caused by pressure spikes.
- Hydraulic System Safety — Relief valves are a critical safety component in hydraulic circuits; using the correct OEM-rated valve ensures the system vents at the proper pressure, protecting hoses, seals, and downstream components from catastrophic failure.
The main relief valve is the hydraulic system's primary pressure-limiting device. It continuously monitors circuit pressure and opens to divert fluid back to the reservoir whenever pressure exceeds the system's rated limit, protecting the pump's hydraulic motor, cylinders, and plumbing from damage caused by excessive force. When a relief valve sticks closed, wears, or loses its calibrated set point, pressure can spike beyond safe limits — causing seal failures, hose bursts, or structural damage to hydraulic components — making timely replacement with a correctly rated OEM part essential for continued safe and productive operation.
