Good photographs can shorten the first round of technical questions, especially when an old component's documentation is missing. The goal is to show identity and interfaces, not simply produce an attractive product image.

Capture the identity clearly

Take a straight-on photograph of the complete nameplate and every suffix in the model code. Include the coil label separately. If a marking is damaged, send the original high-resolution image rather than guessing the missing characters.

Show the interfaces safely

With the component safely accessible under the machine's procedures, document mounting features, ports, connectors and overall orientation. Add a scale reference only where it can be placed safely. A photograph cannot reliably establish a thread specification or an exact mounting tolerance.

Add operating context

Include the machine function and available circuit drawing. State whether the request is for an identical part, an alternative or an unidentified legacy component. Preserve the original images and accompany them with known dimensions and operating conditions.

Practical checklist

• Photograph the full nameplate and separate coil label.
• Show mounting, ports and connectors from useful angles.
• List uncertain details explicitly instead of inventing a model code.

Discuss your application

Explore related hydraulic products, or send JIUDING your model code and application details. Include the circuit drawing and the operating conditions relevant to the checks above so the required configuration can be reviewed.
