The Multiquip EM98222 is a genuine OEM Main Cylinder Pilot Valve designed for LS-series hydraulic-driven concrete pumps, including the LS60TD, LS300, LS300G, LS300GK, LS300P, LS400, LS40D, LS40TD, LS50TD, LS500, LS600, and LS600P. As a direct OEM replacement, part EM98222 is built to the same specifications as the original valve, ensuring correct hydraulic sequencing and pressure response within the pumping circuit. DHS Equipment stocks this part to help keep your concrete pump operating at rated output with no guesswork on fitment.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to exact pressure and flow tolerances required by the LS-series hydraulic circuit, so the valve opens and closes at the correct actuation point every cycle.
- Direct-Swap Replacement — Matches the original valve's port configuration and mounting interface, allowing installation without reworking hydraulic lines or fittings.
- Broad LS-Series Compatibility — Confirmed fitment across a wide range of Multiquip hydraulic concrete pump models including LS60TD, LS300, LS400, LS500, LS600, and related variants.
- Maintains Pumping Cycle Integrity — A properly functioning pilot valve ensures the main cylinders stroke in correct sequence; a faulty valve causes erratic output, pressure loss, or complete pump stoppage.
- Hydraulic System Safety — Correct pilot valve operation is critical to maintaining controlled pressure in the main cylinder circuit; an out-of-spec valve can cause uncontrolled pressure spikes that stress downstream hydraulic components.
The main cylinder pilot valve is a hydraulic control component that directs pressurized fluid to trigger the switching action of the main pumping cylinders in an LS-series concrete pump. It acts as the command signal that tells the main cylinders when to reverse direction, keeping the pumping stroke synchronized and the concrete flowing smoothly through the delivery line. When this valve wears or fails, the pump may lose stroke consistency, produce surging output, or stop cycling altogether — making prompt replacement essential to keeping pours on schedule.
