The Multiquip EM98220 Cycling Valve Assembly, Swing is a genuine OEM component designed for hydraulic-driven concrete pumps in the LS series, including LS40D, LS40TD, LS50TD, LS400, LS500, LS600, LS600P, and LS60TD models. As a direct factory replacement, this assembly meets the original engineering specifications for proper swing-valve operation and concrete flow control. DHS Equipment sources this part directly through authorized Multiquip channels, so you can order with confidence that you are receiving the correct assembly for your machine.
Key Features
- Genuine OEM Valve Integrity — Manufactured to the original hydraulic pressure tolerances and sealing specifications required for consistent swing-valve cycling in concrete pump applications.
- Drop-In Assembly Replacement — Supplied as a complete assembly, allowing direct installation into the swing-valve circuit without sourcing individual sub-components.
- Broad LS Series Compatibility — Confirmed fitment across LS40D, LS40TD, LS50TD, LS400, LS500, LS600, LS600P, and LS60TD hydraulic concrete pumps.
- Consistent Concrete Flow Performance — A properly functioning swing cycling valve directs hydraulic actuation to alternate the pumping cylinders in sequence; a worn or failing valve disrupts this rhythm, causing pressure loss and inconsistent output at the discharge line.
- Hydraulic System Safety — The cycling valve is a critical control point in the hydraulic circuit; using a correctly rated OEM assembly helps prevent uncontrolled pressure events and maintains predictable machine behavior during pumping operations.
The swing cycling valve assembly is the hydraulic control component responsible for alternating the direction of the swing tube inside the concrete pump hopper. As each pumping cylinder strokes, the valve signals the swing tube to pivot and align with the active cylinder, maintaining a continuous flow of concrete toward the discharge outlet. When this assembly wears, seals degrade, or internal components fail, the swing tube loses proper timing, resulting in misfires, pressure drops, and interrupted concrete delivery — issues that can stall a pour and place excessive stress on the surrounding hydraulic circuit.
