Solenoid valve coil compatible with JCB 3CX and 4CX excavators — 24V replacement for OEM part numbers 25221263 and 71720309. Designed as a directfit replacement to restore reliable solenoid valve operation in hydraulic control systems. Key benefits Restores valve actuation and hydraulic control: replaces a failed coil to get your machine back to work quickly. Minimizes downtime: quick swapin replacement that helps avoid extended service delays. Reliable electrical performance: 24V specification matches the original electrical system for proper coil operation and safe switching. Costeffective alternative to OEM: compatible replacement for specified JCB part numbers without compromising fit and function. What it does Converts 24V electrical input into the magnetic field required to actuate the solenoid valve, allowing hydraulic circuits to open or close as intended. Designed to match the form and function of the original coil for consistent valve response and predictable machine behavior. Key attributes Compatibility: Specifically compatible with JCB 3CX and 4CX excavator models. Replaces OEM part numbers 25221263 and 71720309. Voltage: 24 volts DC — must be used where the machine's solenoid system is 24V. Functionality: Solenoid coil for valve actuation in hydraulic systems; intended as a replacement part for excavator solenoid valves. Fit and installation: Engineered to meet OEM fit and mounting requirements for straightforward installation and reliable sealing when mounted on the solenoid valve assembly. Durability: Built for heavy equipment use and designed to withstand the operating environment typical for excavator hydraulic systems. Applications / Use cases Onsite of a JCB 3CX or 4CX with a failed solenoid coil to restore hydraulic controls for digging, lifting, or auxiliary hydraulics. Routine maintenance replacement during hydraulic valve overhaul to ensure consistent valve response and prevent intermittent failures. Fleet service: stocking as a spare part for quick replacement in field service trucks or maintenance shops supporting JCB 3CX/4CX machines. Installation and operation notes Confirm system voltage is 24V before installation. Verify that the coil's part numbers (25221263, 71720309) match the valve assembly or the machine's replacement part list to ensure compatibility. Follow proper safety procedures: disconnect power and relieve hydraulic pressure before removing or installing the coil. Inspect connectors and valve plunger for wear or contamination; or clean as needed to ensure longterm performance.
