The Multiquip EM98227 Check Valve is a genuine OEM component designed for Mayco hydraulic-driven concrete pumps, including the LS600P, LS500, LS600, LS400, LS40D, LS40TD, and LS50TD series. As a direct OEM replacement, the EM98227 is manufactured to the same specifications as the original part, ensuring consistent fluid control performance within the pumping circuit. Sourced directly through authorized Multiquip supply channels, this check valve is the correct factory-matched solution for keeping your Mayco pump operating at spec. Verify your model code against the fitment list above before ordering to confirm compatibility.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original pressure rating and seat geometry required for hydraulic-driven concrete pump circuits, preventing backflow and pressure loss.
- Direct-Fit Replacement — Engineered to match the original port dimensions and connection interface of the LS-series pump hydraulic system for a straightforward swap.
- Broad Mayco Pump Compatibility — Confirmed fitment across LS600P, LS500, LS600, LS400, LS40D, LS40TD, and LS50TD concrete pump models.
- Consistent Flow Control — A properly functioning check valve maintains directional fluid control through the pumping circuit; a worn or failed valve results in backflow, pressure drop, and inconsistent concrete output.
- Pressure System Safety — In a hydraulic concrete pump, a compromised check valve can cause uncontrolled pressure fluctuations — using the correct OEM-spec replacement is critical to safe system operation.
A check valve in a hydraulic-driven concrete pump serves as a one-way gate in the fluid circuit, allowing flow to move in only one direction and preventing backflow that would disrupt pumping pressure and output consistency. In Mayco LS-series concrete pumps, the check valve plays a direct role in maintaining the rhythmic pressure strokes that push concrete through the delivery line. When a check valve wears, sticks, or fails to seat properly, operators will notice reduced output pressure, inconsistent concrete flow, or complete loss of pumping action — all of which point to immediate inspection and replacement of this component.
