50218955 Kit, Pressure Limiting Valve | Jungheinrich DFG/TFG

Overview

The 50218955 Kit, pressure limiting valve is a hydraulic replacement component for Jungheinrich counterbalance forklifts. The pressure limiting valve — often called a relief valve — protects the hydraulic system by capping maximum working pressure, safeguarding the pump, control valves, hoses and lift cylinders against overload. When the valve wears, sticks or drifts out of adjustment, you may notice slow or weak lifting, whining hydraulics or inconsistent mast performance. Fitting a new kit promptly helps restore lift performance and protects downstream hydraulic components from costly damage.

Compatibility

The 50218955 for CD/CL trucks, along with the other ranges listed below, is specified for a broad group of Jungheinrich diesel and LPG forklifts:

• CD/CL 40-50 series
• C/H series
• DFG/TFG 16-20 series
• AK/AS series
• DFG/TFG 40-50 series

Jungheinrich uses the DFG prefix for diesel trucks and TFG for LPG (Treibgas) trucks, so this kit covers both fuel variants within the applicable tonnage classes. Internal components can change between production runs, so always verify fitment against your truck’s model designation and serial number on the data plate before ordering. If you are unsure, share your model and serial details and our team will confirm the correct part.

Quality and Reliability

A pressure limiting valve is one of the most pressure-critical parts in a forklift’s hydraulic circuit, so build quality matters. The 50218955 Kit, pressure limiting valve is supplied with the components required to renew the valve assembly and is engineered to match the original part’s dimensions, seating surfaces and pressure settings. Accurate, consistent pressure relief keeps lifting speeds predictable, protects the hydraulic pump from overpressure and allows the mast and hydraulic circuit to operate as Jungheinrich designed them to.

Installation and Maintenance Tips

• Depressurize first. Lower the mast or attachments fully, shut the truck down and release residual hydraulic pressure before opening the circuit.
• Disconnect the battery and follow the lock-out steps described in your service manual.
• Fit the complete kit. Use the new components supplied rather than reusing worn seals or springs.
• Torque and set correctly. Tighten fasteners and adjust the relief setting to the values in the Jungheinrich workshop manual, then verify with a calibrated test gauge.
• Check the oil. Contaminated hydraulic oil is a common cause of valve seat wear, so inspect oil condition and flush the system if it is heavily soiled.
• Because this is a safety-relevant hydraulic component, fitting by a trained technician is strongly recommended.
