An essential component of the hydraulic system, the 25/222657 solenoid valve by GX-AFTER. It is used in JCB 3CX, 4CX backhoe loaders, and selected telehandler models. It serves a crucial dual function: controlling the sideshift clamp (hydraulic clamp for the excavator arm) and engaging the "tortoise" mode (creep speed or slow arm movements) required for precision work.
GX-AFTER is the smart choice for your machine. We provide high-class replacements that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

When replacing a solenoid valve, we recommend inspecting the condition of the electrical coil, the connector, and the cleanliness of the hydraulic oil. Contaminants are the most common cause of valve failure.
A malfunctioning sideshift clamp solenoid can cause the excavator arm to unexpectedly unlock and move, risking damage to the machine or surroundings. Failure of the "tortoise" function can prevent precise machine operation or safe travel.
The 25/222657 solenoid valve is an electrically controlled valve that directs the flow of hydraulic oil. Depending on the signal from the switch in the cab, the valve opens or closes a circuit. For the **sideshift clamp**, it activates the cylinder that locks the excavator arm to the sideshift carriage. For the **"tortoise" function**, it switches the machine to a low-speed mode (creep speed) for precise arm positioning or slow travel.

This is a hydraulic locking mechanism (clamp) that immobilizes the backhoe arm on its sideshift carriage. It allows the arm to be locked in the center position for travel or in any working position. This solenoid valve controls the pressure to that cylinder.
The "tortoise" function (creep speed) is a slow-operation mode. Depending on the machine, it can limit travel speed (for precise maneuvering) or slow down the arm's working movements (for precise load positioning). This solenoid valve activates this mode.
Yes, solenoid valves of this type are typically sold as a complete unit (mechanical valve + electrical coil). The product photos show the actual component being offered.
