About Kaitai Valve Group Co., Ltd. - Industrial Valves & Gauges Supplier in China

Kaitai Valve Group Co., Ltd. is based in China and lists 18 active valve products in its catalogue. The company’s portfolio covers a variety of industrial valve types, including ball, butterfly, gate, and knife‑gate designs. Products are identified by construction material such as brass, cast iron, carbon steel, stainless steel, PVC, and PTFE. The catalogue differentiates between full‑bore, reduced‑bore, threaded, flanged, wafer, and trunnion‑mounted configurations. Each entry aligns with HS chapter 84, where valve assemblies are classified under headings such as 8481 and 8482.

The listed items span both standard and high‑pressure applications. Examples include a 3‑way full‑bore brass ball valve with threaded ends, a high‑pressure carbon‑steel ball valve, and a stainless‑steel knife‑gate valve for slurry handling. Butterfly valve offerings range from lug‑type to wafer‑type and include PVC and stainless‑steel bodies. The product set also contains gate and trunnion‑mounted ball valves designed for large‑diameter pipelines. This breadth reflects typical Chinese valve manufacturers that serve process, water‑treatment, and agricultural sectors.

Product Range and Specialties of Kaitai Valve Group Co., Ltd.

The catalogue contains 18 distinct valve models, grouped by function and material. Ball valves are offered in brass, cast iron, carbon steel, stainless steel and PTFE‑lined versions, with full‑bore flow paths and standardized NPT or flanged connections. Butterfly valves appear as lug‑type, wafer‑type and clamp‑type, fabricated from PVC or stainless steel, and are sized for quick installation in pipework up to DN 200. Gate and knife‑gate valves are supplied in cast steel and stainless steel, suitable for straight‑through flow and high‑solids environments. Trunnion‑mounted and full‑welding designs target large‑diameter, high‑pressure pipelines.

In the valve industry, ball valves are commonly classified by pressure rating such as ANSI 150 or API 600 and by end‑connection standards like ANSI B16.5 for flanged ends or NPT for threaded ends. Butterfly valves typically meet ISO 5752 for pressure classes and are tested for leak‑tightness at 0.6 MPa for PVC and up to 2 MPa for stainless steel. Gate valves are often rated to ANSI 150 and may use metal‑seated or soft‑seated discs depending on service. PTFE‑lined brass ball valves are used where chemical resistance to acids and alkalis is required, with typical nominal diameters ranging from ½ in to 4 in.

Trade and Export Information - Kaitai Valve Group Co., Ltd.

China is a major exporter of industrial valves, with HS 8481 covering ball, gate and check valves and HS 8482 covering butterfly‑type devices and related fittings. Export shipments from Chinese valve manufacturers frequently target Southeast Asia, the Middle East, Africa and South America, where water‑treatment, mining and agricultural irrigation projects drive demand. Buyers often require compliance with ISO 9001 quality‑management, API 6D for pipeline valves, and CE marking for European markets. Standard packaging includes wooden crates or steel frames, sized for 20‑ft or 40‑ft containers, and shipping terms such as FOB Shanghai or CIF destination are typical.

Regulatory inspection may involve Chinese customs inspection and third‑party testing laboratories that issue mill‑test reports, pressure‑test certificates and material test certificates (MTC). For stainless‑steel valves, buyers usually request mill certificates confirming ASTM A351 or A182 grades, while carbon‑steel valves are checked against ASTM A216. PVC and PTFE components are often verified for compliance with EN 10204 3.1 test reports. These documents support customs clearance and downstream quality assurance.

Sourcing from Kaitai Valve Group Co., Ltd. - Buyer Guidance

When sourcing valves from Kaitai, buyers should request the specific material certificates (e.g., ASTM, GB standards) for each valve body and trim, as well as pressure‑test reports at the rated design pressure. Sample units can be requested to verify end‑connection dimensions, bore size and operating torque. Confirm that the valve’s pressure rating matches the intended system, and check that the connection type (threaded, flanged, wafer) aligns with the buyer’s piping standards.

It is advisable to obtain a declaration of conformity or test report that references the relevant ISO or API standard before placing a full order. Verify the packaging plan, including crate dimensions and moisture‑resistant lining, to prevent corrosion during transit. Typical minimum order quantities for custom‑size valves range from one unit for standard sizes to 10 units for special‑order configurations, with lead times of 4 - 8 weeks depending on material and finish.

What valve types does Kaitai list in its catalogue?

Kaitai lists ball valves made from brass, cast iron, carbon steel, stainless steel and PTFE‑lined bodies; butterfly valves in lug, wafer and clamp styles using PVC or stainless steel; gate valves and stainless‑steel knife‑gate valves; as well as trunnion‑mounted and full‑welding ball valve designs. The catalogue covers both full‑bore and reduced‑bore configurations.

Which HS codes are applicable to these products?

The valve models fall under HS Chapter 84, primarily heading 8481 for ball, gate and check valves and heading 8482 for butterfly‑type valves and related fittings. These codes are used by customs authorities worldwide to classify valve shipments.

What material standards should a buyer verify?

Buyers should ask for mill certificates referencing ASTM A351 or A182 for stainless‑steel, ASTM A216 for cast steel, ASTM B16 for brass, and GB/T 9715 for PVC and PTFE‑lined components. The certificates should also state compliance with the relevant pressure‑class standard such as ANSI 150 or API 600.

Are there typical certifications required for Chinese valve exporters?

International buyers usually request ISO 9001 quality‑management certification, API 6D or ISO 5752 compliance for pressure‑rated valves, and CE marking for products destined for the European Economic Area. These certifications should be confirmed with the supplier before contract finalisation.

What are common packaging and shipping arrangements?

Valves are typically packed in wooden crates or steel frames with moisture‑resistant liners to protect against corrosion. Shipments are loaded into 20‑ft or 40‑ft containers, and Incoterms such as FOB Shanghai or CIF destination are commonly used.

What is a typical MOQ and lead time for standard valve sizes?

Standard valve sizes can often be ordered as single units, while custom dimensions usually require a minimum order of 10 units. Lead times range from four weeks for off‑the‑shelf models to eight weeks for custom finishes or special material specifications.

How can a buyer obtain performance verification before ordering?

Buyers should request a pressure‑test certificate at the design pressure and a hydrostatic test report for each valve type. For stainless‑steel valves, a corrosion‑resistance test result and a mill test certificate are also advisable, and sample units can be evaluated for torque, sealing performance and dimensional tolerances.
