Kyotechs' official site explains the solenoid valve's role in construction machinery — an electrically switched valve that routes pilot oil or fuel on command from the controller. Its store lists solenoid valves as a standing category. The documented extract covers complete valves, a 24V coil and engine shut-off solenoids; note which kind each number is before ordering, because a coil alone does not cure a stuck spool.

Coil, Valve or Wiring?
Before ordering, the cheap checks: measure the coil's resistance, confirm voltage actually reaches the connector, and inspect the connector pins. A solenoid that tests fine on the bench but never receives power is a harness or controller fault. If the coil is burnt or the spool is scored, replace the unit the listing describes — valve, coil or shut-off solenoid — and keep the old number for the record.
Delivery and preparation times are confirmed for your order in the enquiry reply, in writing and before payment: the reply states the times, the packing and the shipping method that apply to your exact part number. Times are confirmed per order rather than published as a general figure, because they follow the listing, the quantity and the destination.
Frequently Asked Questions
How do I know whether I need the valve or just the coil?
If the coil is open-circuit or shorted and the spool moves freely by hand, a coil can be enough — the Volvo listing above is a coil. If the spool sticks or the valve leaks internally, order the complete valve. Describe your test results and the reply will match the right listing.
Does voltage matter?
Yes — the documented listings include both 12V and 24V units, and they are not interchangeable. State the machine's system voltage with the part number.
Do the parts carry a warranty?
Warranty terms are confirmed in writing for each order before payment. Kyotechs' own FAQ states that most parts are backed by a warranty against manufacturing defects; ask for the term that applies to your listing when you enquire.
Specifying Solenoids Without Errors
Solenoid orders go wrong on three details, all cheap to check. Voltage: machine systems are 12V or 24V and the documented listings include both — quote yours. Function: a proportional solenoid, a switching solenoid and an engine shut-off solenoid are different devices doing different jobs, and their names are not interchangeable. Connector: pin count and connector shape vary between models that share an engine. The old unit answers all three questions — its label carries the number and voltage, and a photograph of its connector closes the rest. Include those in the enquiry and the reply matches a listing, not a likelihood.
Testing a suspect solenoid takes minutes and saves the order entirely when the coil is innocent. A multimeter across the coil shows open circuit on a burned coil and a plausible resistance on a healthy one; a healthy coil with no movement points to a stuck spool or a supply problem upstream. State the result in the enquiry — it changes the answer from a solenoid to a diagnosis, and this site's replies are written to make that distinction rather than complete a sale that cannot fix the machine.
