D513680 Solenoid Valve for Doosan D15/18S5 & D20/25/30/33S5

Overview

The D513680 Solenoid Valve is a Doosan-branded replacement component for the hydraulic control systems of Doosan diesel forklifts. This electrically operated valve regulates fluid flow by opening and closing in response to signals from the truck’s control system, helping the forklift lift, lower and travel smoothly and predictably. When a solenoid valve begins to fail, operators often notice sluggish hydraulics, intermittent function or fault codes, so replacing a worn unit promptly is one of the simplest ways to avoid unplanned downtime. The D513680 installs in place of the original valve on the listed S5-series and SC-series machines without modification.

Compatibility

This solenoid valve covers a broad cross-section of the Doosan counterbalance range:

• D15/18S5 – compact 1.5–1.8 tonne S5-series models
• D20SC-5 (SB1089) and D20SC5 (SB1127) – SC-series trucks
• D20/25/30/33S5 – the 2.0 to 3.3 tonne S5-series family
• D35C5 (SB1092, Cummins B3.3 engine) – 3.5 tonne class

Some of these model codes apply to specific engine or serial prefixes (SB1089, SB1127, SB1092), so we recommend checking the part number and prefix on your machine’s data plate before ordering. If you need help confirming that the D513680 for D15/18S5 or any other listed truck matches your unit, our team is happy to assist.

Quality and Reliability

As a Doosan-branded part, the D513680 Solenoid Valve is produced to the manufacturer’s original specification. Coil winding, seals and valve-body machining all influence solenoid performance, and parts built to specification help maintain the response times and flow rates your forklift’s hydraulic circuit was designed around. Fitting the correct numbered part, rather than an unverified alternative, reduces the risk of electrical faults, leaks and repeat repairs over the life of the truck.

Installation and Maintenance Tips

• Depressurize the hydraulic system and disconnect the battery before starting work.
• Clean around the valve body before removal so dirt cannot enter the hydraulic circuit.
• Disconnect the electrical connector carefully and note the original wiring and hose routing.
• Fit the new valve with suitable thread sealant where required and torque fasteners to specification.
• After installation, cycle the valve, check for leaks and confirm correct actuation.
• During routine service, inspect connectors and wiring for corrosion or chafing, which can mimic solenoid failure.
