Kailing Factory Visit: Product and Document Review Checklist
Planning a supplier visit? Confirm the itinerary and the records you want to review before travelling.
Short answer: Ningbo Kailing Pneumatic Co., Ltd. (KAILING / KLQD) is located at Xikou Industrial Park, Fenghua, Ningbo. Arrange a visit to review the relevant production areas, the exact product configuration, available inspection records and applicable documents. Agree the visit scope and sample arrangements in advance; company documents do not establish coverage of every model.
What buyers actually worry about
By the time a buyer books a factory visit, price is already in range. The questions still blocking the order are different, and a visit answers them faster than any email thread.
| The buyer's question | What the visit has to prove |
|---|---|
| Is this a factory, or a trading desk with a rented showroom? | You want to see the machine that cuts the valve body, not a reception area. |
| Will the tenth batch perform like the sample I approved? | Sample quality is easy; batch consistency is the hard part, and it comes from fixed tooling and recorded parameters. |
| Are the certificates real, current, and do they cover my exact model? | A report with no model scope is a piece of paper. Scope, date and issuing body must all match the part number. |
| If a valve leaks eight months later, who answers, and how fast? | This is where most suppliers go quiet. Ask for traceability and a named response path. |
| Can they build my version without a six-month project? | OEM competence shows in the first article, not in the brochure. |
Below is what we show, and what you should ask for while you are here.
The company behind the catalogue
The published company address is No.13 ZongYan Road, Xikou Industrial Park, Fenghua, Ningbo. Ask to review the relevant company certificate, its holder, site address, scope and validity against your order.
Ask which valve-body and cylinder machining, coil production, assembly and testing steps apply to the models you plan to order. Verify which are performed at this site, which are purchased or subcontracted, and how incoming and outsourced items are identified and inspected. Factory photographs alone do not establish the complete manufacturing boundary.
The range covers 14 product families in total, supplied as standard catalogue parts or as OEM builds:
| Product family | Series / models | Typical use |
|---|---|---|
| Angle seat valves | KLJZF 15–40 | Filling, rinsing, dosing and steam-adjacent process lines |
| Solenoid valves | 2W, 2WB, 2V, 4V and related series | Fluid control and directional control |
| Pneumatic actuators | AT series rack and pinion | Actuated ball and butterfly valves |
| Electric actuators | KLST (B / R / A / S types) | Valve automation where no air supply exists |
| Pneumatic cylinders | Standard, compact, guided | Assembly, packaging, material handling |
| Air preparation (FRL) | AC / BC 1000–5000 | Air treatment ahead of valves and cylinders |
| Fittings, tubing, accessories | Series-dependent | Circuit completion and retrofit work |
These families serve six industries: food and beverage, water treatment, industrial automation, pharma and lab equipment, chemical process lines, and OEM equipment building.
Confirm current stock, repeat-order configuration and a written schedule for the actual model and quantity. A catalog listing is not evidence that every standard item is available for immediate dispatch.
What you can see on the production floor
A visit follows the route a part actually takes:
| Stage | What happens | What to ask while you are standing there |
|---|---|---|
| Machining | Verify the actual machining steps and equipment used for the quoted valve or cylinder | How often is tooling replaced, and which dimensions are checked per lot? |
| Assembly | Review the assembly instructions, specified tightening requirements and traceable material/ seal selection for the quoted model | Are operators trained per station, and is the assembly area separated from machining? |
| Testing | Review the agreed function/leakage test scope, sampling or unit-test plan, conditions and retained records for the ordered model | Can you show me a unit that failed and was pulled? |
| Stock and dispatch | Confirm stock, packing specification, moisture protection and the dispatch plan for the actual order | How are mixed orders consolidated and labelled? |
At the test station, request the applicable procedure, identified sample, test conditions and retained results. Compare those records with the agreed order requirements.
What the documents prove, and what they do not
Review the relevant documents below and ask which copies are available for the exact quotation. Match each document to its holder, scope, model and date:
| Document | Standard / reference | Scope to confirm before you accept it |
|---|---|---|
| ISO 9001 | Quality management system, design and manufacture of pneumatic components | Certificate holder name and site address must match the invoice issuer |
| CE EMC verification | Directive 2014/30/EU | Applies to the solenoid valve series, not to actuators or cylinders |
| RoHS reporting | Review the dated original report | Match the tested model, holder and report scope to the actual order; a report date alone does not prove every model is covered |
| IP test report | Review the original report and identified sample | The available GQDW20240159 report identifies an S91B/DC24V sample and Ningbo Kaihang Electronic Technology Co., Ltd.; it does not establish all 2WB valves as IP67 |
| Export packaging | Review the dated records and destination requirements | Existing German/French records are historical 2023 documents; current-year applicability needs confirmation |
One caution we would rather state ourselves: certificates have scope. Match each report to its exact holder, sample, model and configuration. An EMC model list does not establish pressure/material ratings; an S91B enclosure sample report does not establish all 2WB valves as IP67. Ask which models each document covers and where application testing is still needed. A supplier who cannot answer that question is handing you the risk.

What happens when something goes wrong
This is the section most suppliers leave out, so here is ours.
| Situation | What happens |
|---|---|
| Traceability | Ask which batch, production, material and inspection records can be linked to the ordered model and shipment, and agree the identification to retain. |
| Nonconforming unit found in-process | Request the procedure and available example records for identifying, segregating and resolving a nonconforming item. |
| Technical question from a buyer | Sales will review the supplied requirements and confirm the review schedule. |
| RFQ | Confirm quotation timing after model, configuration, quantity and required documents are reviewed. |
| OEM quality documents | A written quality agreement or PPAP-style document set is confirmed case by case before the order is placed. |
If you need a written quality agreement or a PPAP-style document set for an OEM programme, raise it during the visit and we will confirm exactly what can be provided before you place the order.
OEM and ODM without the drama
Agree the project-specific review and approval steps in writing; use the following topics to define the scope:
| Step | What happens | Output you receive |
|---|---|---|
| 1. Drawing review | Model, materials, interfaces and tolerances checked against machine capability | Feasibility reply with open questions |
| 2. Material and configuration | Seal compound, body material, coil voltage and marking method fixed | Written specification |
| 3. Sample or first article | Confirm how the sample will be made and inspected, and which production conditions it represents | Sample with inspection data |
| 4. Approval | Buyer tests and signs off | Approved first article record |
| 5. Mass production | Agree the release criteria, approved configuration, marking and packaging for the order | Batch with traceable records |
Lead times are quoted against the specific model, quantity and configuration, and confirmed in the quotation rather than as a general figure. Confirm stock for repeat orders and agree drawing/sample approval dependencies for an OEM request. Minimum order quantity depends on what actually changes — a marking change and a body redesign are two different projects, and both are stated in writing before you commit.
Bring drawings, expected quantities and target dates to the visit so the technical and commercial review can be scoped; agree outstanding actions and timing in writing.
From the Canton Fair to the plant
Confirm current flight/train schedules, transfer time and the agreed factory appointment before booking. Travel time depends on the route and operating conditions; request the current address and meeting arrangements.
| Visit arrangement | What to confirm before booking |
|---|---|
| Arrival point and route | Confirm the current airport or railway connection and the actual meeting address |
| Transfer to the site | Agree the transfer provider, meeting point, timing and any charges separately |
| Time on site | Agree the document, production, sample and drawing review that can be scheduled |
| Invitation or visit documents | Ask whether the requested document can be supplied and what information and processing time are needed |
| Other visits | Coordinate the appointments with the responsible contacts before finalizing the itinerary |
Before you come
Send your travel dates, the product families and annual volumes you are sourcing, and any drawings or target specifications. If you want a specific demonstration, ask in advance which test, equipment and responsible staff can be arranged. Bring the sample and drawing for review, and agree any outstanding quotation and scheduling actions separately.

FAQ
Is Ningbo Kailing Pneumatic a manufacturer or a trading company? Review Kailing’s business identity, relevant production steps and site through an agreed visit or video walkthrough. Match the company name and site address to the business and certificate records, and ask which steps apply to the models being ordered.
What can I review during a factory visit? Agree which relevant production areas, model documents, inspection records and samples can be reviewed. Check each report’s holder, sample, model, date and scope; the available S91B report is not blanket IP67 evidence for the 2WB series.
How far is the factory from the Canton Fair? Confirm the current route, schedules and transfer time before booking. Agree the factory appointment and allow time for the intended document, sample and drawing review.
Is every valve tested, or only a sample? Request the inspection plan and sample records for your exact model. Confirm which checks are performed per unit or per lot, the test conditions, acceptance criteria and how nonconforming items are handled.
What is the lead time for repeat and OEM orders? Confirm stock and a written dispatch schedule for the exact repeat-order model and quantity. OEM and ODM projects add drawing review, sampling and first article approval before mass production. The exact schedule depends on model, quantity and whether custom marking or packaging is required, and is confirmed in the quotation.
Do I need to speak Chinese to visit? State your preferred language and which drawings, test reports or certificates need translation. Confirm the available staff, document language and visit arrangements before booking.
