The most useful photograph in a valve inquiry is often not the one of the nameplate. It is the one that shows the full bank in order, with enough room around it to identify where the controls and hoses connect. For a buyer checking the XCMG QYZTF-S10E multiway valve 803000096, that photograph belongs alongside the nameplate and the crane serial number. The reference identifies a catalog entry; it does not settle the configuration of a particular crane.
Ask the workshop for a picture of the complete valve bank in its installed orientation. Mark a clear starting end and number the sections in sequence. If the technician can identify the function of each section from the machine documentation, write it beside the number. Leave unidentified functions marked unknown rather than copying names from a similar crane. Two images taken from opposite ends are useful only if the supplier can tell how they relate to each other.
Show any visible port markings, actuators and electrical connections in separate photographs. Give those photographs the same section numbers as the overview. When a marking is hard to read, keep a photo of the surrounding casting and note where it was found. If the bank has been changed in a previous repair, attach the drawing or invoice if available, but distinguish that record from what is fitted now. The objective is to give the parts desk a map it can use, not to produce a new hydraulic diagram.
One supplier may price a complete crane hydraulic control valve while another quotes only a section or a component fitted to it. Ask each supplier to name the offered reference and mark the included pieces on a photograph or drawing. If the technician needs a particular actuator, fitting or other separate item, put it on the request by name. Do not treat an accessory visible in a product image as part of the deal unless the quotation says so.
If a single crane movement is the reason for the inquiry, tell the supplier which function the workshop has identified. Do not put “complete bank faulty” on a purchase order unless that diagnosis has been made. The buying decision and the service diagnosis are separate. No one should open lines or operate the equipment simply to obtain sales photographs. Inspection, servicing and acceptance belong to the qualified team using the applicable machine documentation.
Request the supplied reference, section order and the evidence for any proposed substitution. “Same body” does not establish that the sections or controls match. Ask the supplier to flag differences, not just describe similarities. Pass the marked quote to the technician who approves fitment before purchasing substitutes a new number. If the match cannot be established, keep the line on hold instead of asking stores to resolve it when the shipment arrives.
For receiving, keep the approved marked drawing and the expected packing list together. Check the label, the visible orientation of the bank and the separately packed items before releasing the delivery to the workshop. Record any mismatch while the package can still be identified. That written trail matters if several visually similar valves arrive in the same delivery or if the original assembly has already been sent out for evaluation.
Use the number to start the search. Confirm the ordered configuration against the crane serial number, the valve markings and the section layout before approving the quote. If any of those details conflict, ask for a documented match rather than guessing from photos.
If a supplier asks for a second view, send the original marked photo back with the new angle. Keep the same numbering rather than starting again from the opposite end. That small detail saves a second round of questions when two people are reviewing the same bank from different sides.
Put the marked valve-bank photo on the crane parts work order. When the supplier quotes one section instead of the whole bank, use the line-by-line quote comparison to record the difference. For a transmission valve enquiry, see the ZF 4WG180 valve ordering guide.
