About Zhejiang Ronze Valve Co., Ltd - Light & Medium Machinery Supplier in China

Based in China, Zhejiang Ronze Valve Co., Ltd lists five distinct steam trap models in its catalogue. The active product count of five reflects the company’s focus on Light & Medium Machinery equipment, specifically steam trap solutions. The catalogue includes an adjustable constant temperature type steam trap, a bimetal strip type steam trap, a bell‑shape float type steam trap, a high temperature and pressure disc type steam trap, and a lever ball float type steam trap. Each item is identified by its functional description rather than a model number in the supplied data. These products are classified under the broader HS chapter 84 for valves and fittings.

The five steam trap types cover a range of operating principles, from temperature‑controlled displacement to float‑based condensation removal. Adjustable constant temperature traps are typically used where precise condensate removal is required, while bimetal strip traps respond to temperature changes in the steam line. Bell‑shape float traps and lever ball float traps provide mechanical float action for medium‑pressure applications, and disc type traps are suited for high‑temperature, high‑pressure environments. The supplier’s listing does not provide specific material or pressure ratings, but the product titles indicate the intended functional categories within industrial steam systems.

Product Range and Specialties of Zhejiang Ronze Valve Co., Ltd

Zhejiang Ronze Valve’s catalogue comprises five steam trap designs that correspond to the main categories used in the valve industry. Adjustable constant temperature traps are usually constructed from stainless steel (e.g., 304 or 316) and operate up to 250 °C and 1 MPa, with a typical inlet pressure rating of 1.5 MPa. Bimetal strip traps employ a brass or bronze bimetal element and are commonly rated for 150 - 200 °C and pressures up to 0.8 MPa. Bell‑shape float traps are often cast iron or carbon steel, handling temperatures up to 180 °C and pressures of 1 MPa.

High temperature and pressure disc‑type traps are generally made of alloy steel or high‑grade stainless steel, supporting temperatures of 300 °C and pressures of 2 MPa or higher, and they provide quick opening action. Lever ball float traps combine a ball valve with a float mechanism, typically rated for 200 °C and 1.2 MPa, and are used in medium‑duty condensate removal. Industry standards such as API 617 for steam traps and ASME B16.34 for valve dimensions are commonly referenced when specifying these products, and buyers often compare parameters like inlet pressure, temperature range, and discharge capacity (e.g., 100 L/min).

Trade and Export Information - Zhejiang Ronze Valve Co., Ltd

Steam traps fall under HS code 8481, which covers valves, taps, cocks and similar devices. China is a leading exporter of industrial valves, and shipments of steam traps are regularly dispatched to Europe, North America, and Southeast Asian manufacturing hubs. Buyers typically require compliance with CE marking for the European market and UL or CSA certification for North America, along with material test reports confirming stainless‑steel grades. Standard packaging involves wooden crates or steel pallets sized for 20‑ft or 40‑ft containers, with FOB or CIF terms most frequently used.

Regulatory inspections often reference ISO 9001 quality management systems, although the supplier’s own certifications are not listed in the provided facts. Importers should verify that the steam traps meet API 617 performance criteria, especially for high‑temperature and high‑pressure disc types. Customs documentation usually lists the HS code 8481.90 and includes a commercial invoice, packing list, and certificate of origin, which Chinese exporters commonly provide.

Sourcing from Zhejiang Ronze Valve Co., Ltd - Buyer Guidance

Prospective buyers should request detailed product data sheets that specify material composition, operating temperature and pressure ranges, and discharge capacities for each trap model. Test reports such as a pressure‑tightness test at the rated pressure and a condensate discharge test are standard documents that help confirm performance. Because certifications are not disclosed for this supplier, buyers are advised to ask for any CE, UL, or API compliance certificates before placing an order.

Sampling policies for steam traps typically allow a single unit per model to be shipped for trial, with lead times of four to six weeks from order confirmation in Chinese manufacturing settings. Minimum order quantities are often low for specialized trap types, sometimes as low as one piece, but the exact MOQ should be clarified with the supplier. Verify that packaging protects the valve bodies from impact and moisture, and confirm container loading plans to avoid damage during sea freight.

What steam trap models are listed by Zhejiang Ronze Valve Co., Ltd?

The catalogue includes an adjustable constant temperature type steam trap, a bimetal strip type steam trap, a bell‑shape float type steam trap, a high temperature & pressure disc type steam trap, and a lever ball float type steam trap.

Under which HS code are these steam traps classified?

Steam traps are classified under HS chapter 84, specifically HS code 8481 for valves, taps, cocks and similar devices.

Which material grades are typically used for the constant temperature and disc type steam traps?

Constant temperature traps are often made from stainless steel grades 304 or 316, while high‑temperature disc traps commonly use alloy steel or stainless steel grades such as 316L to withstand temperatures up to 300 °C.

What certifications should a buyer request for these steam traps?

Buyers usually request CE marking for European shipments, UL or CSA certification for North America, and API 617 compliance for performance, together with material test certificates.

What are the typical operating pressure ranges for the listed trap types?

Bimetal strip and bell‑shape float traps are generally rated up to 0.8 - 1 MPa, constant temperature and lever ball float traps up to 1.2 - 1.5 MPa, and high‑temperature disc traps can handle 2 MPa or higher.

How are the steam traps typically packaged for export?

Export shipments are usually placed in wooden crates or on steel pallets, sized to fit standard 20‑ft or 40‑ft containers, with protective padding to prevent impact damage.

What is a common lead time for an order from this supplier?

Lead times for Chinese valve manufacturers are typically four to six weeks from order confirmation, depending on order size and required documentation.
