50453426 Valve Control System for Jungheinrich EJC 110/112

Overview

The 50453426 Valve control system is a replacement hydraulic control unit for Jungheinrich electric stacker trucks. This component regulates oil flow and pressure to the mast’s lift and lower functions, delivering smooth, proportional load handling every time the controls are operated. When a valve control system wears out, symptoms such as slow lifting, fork drift, jerky movement, or unresponsive hydraulics often appear. Fitting a new 50453426 for EJC trucks restores precise metering and dependable performance, helping your Jungheinrich stacker return to full working order.

Compatibility

The 50453426 valve control system is specified for the following Jungheinrich EJC electric stacker series:

• EJC 110/112 series
• EJC 110/112 (Qingpu) production variant
• EJC 110n/112n series

These compact electric stackers share a common hydraulic platform, so this control unit covers the 110 and 112 capacity variants across both the standard series and the later n-generation trucks, as well as units produced at the Qingpu facility. Because Jungheinrich revised components over time, always check the data plate on your truck and confirm part number 50453426 before ordering. If you are unsure, our team can help verify fitment using your truck’s serial number.

Quality and Reliability

As an original Jungheinrich part number, the 50453426 valve control system is produced to the manufacturer’s dimensional and performance specifications. Internal channels, spools, and seats are machined to tight tolerances so that hydraulic oil flows exactly as the EJC’s control electronics expect. That precision translates into consistent lifting speeds, stable load holding, and reduced internal leakage across the component’s service life. Choosing the specified part rather than an unverified alternative also helps protect surrounding components such as the pump, hoses, and cylinder seals from abnormal pressures.

Installation and Maintenance Tips

• Depressurize the hydraulic circuit and disconnect the battery before starting any work.
• Photograph hose routing and electrical connections to make reassembly straightforward.
• Replace sealing rings and O-rings during fitting; never reuse hardened or damaged seals.
• Top up with clean hydraulic oil that meets Jungheinrich’s specification.
• After installation, bleed the circuit, then cycle the lift and lower functions slowly while checking for leaks.
• Inspect the valve area regularly to catch seepage or contamination early.

Valve work on high-lift trucks should always be carried out by a trained technician in line with the truck’s service manual.
