The Multiquip EM23411 Valve is a genuine OEM component designed for Mayco concrete pump models including C30HD, C30HDN, C30HDNI, C30HDG, C30HDZ, LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD. As a factory-sourced part, it meets the exact material and dimensional specifications Multiquip requires for reliable concrete pump operation. Sourced directly through an authorized Multiquip dealer, the EM23411 is the correct replacement when your original valve shows signs of wear, leakage, or pressure loss. DHS Equipment stocks genuine Multiquip parts so you can get the right component the first time and get your pump back to work.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact material and pressure-tolerance specifications for concrete pump valve applications, ensuring consistent flow control and sealing performance.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the original valve position, allowing straightforward installation without rework or adaptation to the pump's hydraulic or mechanical circuit.
- Broad Mayco Pump Compatibility — Confirmed fitment across C30HD, C30HDNI, C30HDG, C30HDZ, C30HDN, LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD concrete pump models.
- Maintains Pump Output Pressure — A properly functioning valve sustains the pressure differential required for consistent concrete delivery; a worn or failing valve results in pressure bleed-off, irregular output, or complete flow loss.
- Fluid-System Safety — Correct valve operation is critical in concrete pump circuits where uncontrolled pressure release can create hazardous conditions for operators and nearby personnel.
In a concrete pump, the valve controls the direction and flow of concrete or hydraulic fluid through the pump's circuit by opening and closing at precise intervals during each stroke cycle. It works in coordination with the pump's drive mechanism to ensure material moves consistently from the hopper toward the delivery line under controlled pressure. When a valve wears, cracks, or fails to seat properly, the pump loses the pressure needed to push concrete through the line — resulting in sluggish output, backflow, or a complete stoppage that halts the pour.
