Solenoid Valve Coil R988124038 — 24VDC, 1 Piece

Rexroth-style · Hydraulic Solenoid Coil · 24VDC · 1 Piece · In stock

The R988124038 is a 24VDC wet-pin solenoid valve coil designed for Bosch Rexroth hydraulic proportional and directional control valves. It is a direct replacement for the original Rexroth coil used on 4WE6 / 4WE10 directional valves and the proportional pressure / flow valves in the 3DREP, 4WRP and 4WRE families. KOEED stocks this coil as a low-power 24VDC switching element suitable for PLC-driven hydraulic systems in injection-molding, press, metal-forming, machine tool and general motion-control applications.

For the equivalent electrically and mechanically, the coil can be driven by a 24VDC discrete output from any of the nine KOEED-supported automation platforms, including Allen-Bradley ControlLogix and CompactLogix, Siemens SIMATIC S7-1200 / S7-1500, Mitsubishi MELSEC, Omron SYSMAC and Schneider Modicon digital output modules — see the Related Modules section for typical driver pairings.

Key Specifications

Datasheet Highlights

• 24VDC wet-pin design — the coil is fully encapsulated, allowing it to operate with the valve tube immersed in hydraulic oil inside the manifold, with no additional sealing required at the stem.
• Direct-fit replacement for the original Bosch Rexroth coil supplied with 4WE6 / 4WE10 / 3DREP / 4WRP directional and proportional valve assemblies, including long-running press and injection-molding cells where the original coil has been damaged by heat, oil ingress or mechanical impact.
• Low-power 24VDC switching makes the R988124038 directly compatible with the 24VDC discrete outputs of any standard PLC, including Allen-Bradley 1756-OB16E, Siemens 6ES7 222-1BH32 and Mitsubishi QY81P output modules — no interposing relay required for short wiring runs.
• Knurled-nut retention allows the coil to be replaced on a live hydraulic system for scheduled maintenance: de-energise, unscrew the lock nut, slip the coil off the tube, fit the replacement and re-energise — typically less than 5 minutes per valve.
• Oil- and heat-resistant encapsulation suited to the elevated ambient temperatures of injection-molding, die-casting, hydraulic press and metal-forming cabinets, where coil surface temperatures can exceed 60 °C during continuous duty.

Typical Applications

• Injection-molding machines — clamp and ejector directional control valves in plastic injection molding, where the R988124038 drives clamp open/close, ejector advance/retract and core-pull sequences.
• Hydraulic presses — directional valves in metal-forming, forging, stamping and briquetting presses, where a 24VDC PLC output commands the press stroke and the coil switches the main directional stage.
• Die-casting and foundry cells — proportional and directional valves controlling shot, intensification and die-spray, often driven from a Siemens SIMATIC S7-1500 or Mitsubishi MELSEC iQ-R controller.
• Machine tools and CNC hydraulics — turret, tailstock, chuck, tool changer and pallet changer hydraulic functions, integrated with Fanuc or Siemens Sinumerik CNC controllers.
• Marine and offshore hydraulic systems — deck machinery, hatch covers and steering hydraulic directional valves where a robust 24VDC coil is required.
• Material handling and mobile hydraulics test rigs — lab and field test stands for hydraulic proportional valves, where the R988124038 is used as the standard 24VDC drive element.

Related Modules & Cross-Reference

The R988124038 is the field-replacement coil for Bosch Rexroth hydraulic directional and proportional valves. The 24VDC switching side is typically driven from a 24V discrete output of an industrial PLC or motion controller. KOEED stocks the related PLC output modules, motion controllers and servo systems below — mixing the coil with any of these gives a complete hydraulic-axis control package from a single BOM.
