Schwing Spare Parts CARTRIDGE PRESSURE 98359417

This pressure cartridge valve, OEM part number 98359417, is a core hydraulic spare exclusively matched to Schwing truck and trailer concrete pumps. It serves as the built-in pressure control insert inside main manifold blocks, regulating system hydraulic pressure to stabilize pumping cycles on busy construction sites. Every dimension, thread pitch and sealing groove follows original Schwing factory drawing standards for direct plug-and-fit replacement without manifold modification.

Heat-treated alloy steel forms the valve core and threaded body, paired with high-temperature resistant elastomer seals that stand up to continuous high-pressure hydraulic oil circulation. The precision ground spool minimizes internal leakage, eliminating gradual pressure drop that would slow concrete delivery or trigger unstable boom movements. Its compact cartridge design saves manifold space while resisting vibration and abrasive oil contaminants common in pump hydraulic circuits.

Field technicians rely on this cartridge to resolve typical hydraulic faults including fluctuating pumping pressure, weak S-valve shifting and frequent safety relief triggering. When original internal pressure control fails, swapping in 98359417 restores uniform system pressure output, cutting unplanned machine downtime on high-volume pouring projects. No extra calibration tools are required after standard installation.

Fully tested under site-grade working pressure before shipment, this spare maintains steady pressure threshold across long shifts of continuous pumping. It tolerates wide temperature swings and dirty construction working environments, delivering consistent performance far longer than generic uncalibrated alternatives. All internal clearances match Schwing’s original pressure curve to protect expensive hydraulic pumps and cylinders from overload damage.

This replacement cartridge fits most mainstream Schwing concrete pump series and ships complete with matching O-ring seals for one-step service. Using genuine-spec hydraulic spares like 98359417 preserves full machine operational efficiency and avoids premature wear to surrounding hydraulic components. It is stocked for fast dispatch to support quick on-site maintenance for pump fleets worldwide.
