Specify three connected layers
Shunfa identifies itself as a pneumatic-component producer. Its published scope includes air-preparation units, solenoid valves, actuating components and accessories, with machinery among its stated applications. [1] For a construction-equipment auxiliary system, the responsible designer must establish suitability. No excavator, concrete plant or particular machine installation is documented here.
The result should be a configuration the buyer can evaluate. A component offer does not replace the machinery designer’s circuit and safety review.
Resolve the catalogue’s model ambiguity
Two reviewed entries share the heading “4V series solenoid valve,” but show different controls. Entry 87 pictures a coil-operated 4V210-08; entry 94 pictures a pull/push control labelled 4R210-08. [2] [3] “The valve on the 4V page” is therefore an ambiguous order description.
| Include | What it resolves |
|---|---|
| URL and marked model | Distinguishes the chosen photograph from similarly titled entries. |
| Symbol and reset method | Confirms the switching function and control type. |
| Coil and connector codes | Makes supply, power and included connector a defined configuration. |
| Dimensioned drawing | Checks port connections and footprint; a suffix alone proves neither. |
Festo’s explanatory material distinguishes valves by ports, positions and actuation; coil count alone does not establish stable switching behaviour. [6] This frames the enquiry. Festo dimensions and performance are not transferred to Shunfa.
Request evidence for the actual supply route
The introduction describes development, processing and sales, and the workshop gallery supplies photographs. [1] [4] Neither identifies every operation performed on a particular valve or the source of each component.
The website refers to ISO 9001:2008 management requirements. No reviewed current certificate or issuing-body verification establishes valid present certification. This historical wording is not used as a quality badge or valve approval.
Approve a configuration you can reorder
- Record identity. Match valve label, coil label, connector and supplied accessories to the accepted quotation. Retain photos and revision.
- Agree functional checks. Set test conditions and acceptance criteria with the responsible designer. Request applicable supplier switching, leakage and electrical inspection methods; no measured result was provided by the reviewed source.
- Check installation. Review mounting, port access and cable/connector clearance against the approved drawing. Do not use a live machine as an improvised test fixture.
- Control changes. Preserve the approved parts list and sample records. Require notice of changes to coil, seal, body or connector before accepting a substitute.
Flow, temperature, duty, protection and cycle-life limits need model-linked data. Stock, price, quantity, dispatch and warranty remain quotation matters. A contact number does not establish overseas service coverage.
Separate legal identity from business history
The exact Chinese entity is 宁波奉化溪口顺发气动工程有限公司. Business-registration data and the official contact page both locate it in Xinjian Village, Xikou, Fenghua. [5] Registration data gives incorporation on 11 April 2017; the website claims a 2008 business origin. The reviewed sources do not establish a predecessor relationship. The earlier year is not presented as incorporation of this legal entity.
Ask the offer to identify manufacturer, contracting entity, invoice issuer and collection site. Placeholder-looking email cells remain preserved in the raw import and are not promoted to verified contacts.
