2025,03,29

Regarding the customization of stainless steel valves, the following is detailed information compiled based on search results:

1、 Customized service scope

Valve type

Ball valves (such as three-way, four-way, and five way ball valves), gate valves, globe valves, check valves, butterfly valves, plug valves, vacuum valves, etc.

Special designs: high platform ball valves, fixed ball valves, fluorine lined ball valves, pneumatic/electric control valves, etc. (as summarized in sections 1, 3, and 7).

Parameter customization

Material: 304, 316, 316L stainless steel (corrosion-resistant), supports special alloys such as chromium nickel stainless steel (as stated in Abstract 8).

Connection methods: thread (screw thread), flange (American standard/national standard), welding, clamp (sanitary grade), etc. (as stated in Abstract 1, 2, 4).

Pressure rating: ranging from low pressure (1.0MPa) to high pressure (400MPa), suitable for different working conditions (such as abstracts 5 and 6).

Size specifications: DN15 to DN100 and above, supporting non-standard sizes (such as abstracts 1 and 7).

Functional requirements: Special designs such as explosion-proof, fireproof, insulation, and leak proof (as summarized in sections 3 and 7).

2、 Applicable industries

Industrial fields: petroleum, chemical, power, metallurgy, mining, etc. (as summarized in sections 2 and 5).

Food and medicine: Sanitary grade quick release ball valves and butterfly valves, in compliance with GMP standards (as stated in abstracts 1 and 4).

Environmental Protection and Water Treatment: Corrosion resistant valves suitable for acidic and alkaline media (as stated in Abstract 4).

Special scenarios: vacuum system, high-temperature steam, high-pressure fluid control (as summarized in sections 3 and 6).

3、 Customization process and precautions

Requirement communication

Provide operating parameters (medium, temperature, pressure, connection method, etc.).

Clearly define design requirements (such as manual/pneumatic control, material standards).

Manufacturer selection

Recommended manufacturer:

Zhejiang Gebang Valve: Provides non-standard valves and fittings, covering the chemical and petroleum industries (Abstract 2).

Shanghai Langao Valve: Supports over 200 non-standard products and provides technical support (Abstract 3).

Zhejiang Kewena Valve: produces national and American standard valves with rich experience (Abstract 4).

Alibaba platform: direct connection with manufacturers, transparent pricing (Summary 1).

Quality and after-sales service

Choose a manufacturer that has passed ISO certification and provide a third-party testing report (as shown in Abstract 3).

Confirm the after-sales service terms (such as installation guidance, warranty period).

4、 Price reference

Ordinary customization: One piece threaded Ball valve costs about 55-136 yuan, while flange ball valve costs 80-1000 yuan (as stated in Abstract 1).

Special requirements: Pneumatic/electric valves and high-pressure valves are relatively expensive (such as pneumatic flange ball valves priced between 168-1000 yuan, Summary 1).

Mass customization: discounts can be negotiated with manufacturers (such as Summary 1 and 3).

5、 Precautions

Material selection: Choose 304 or 316 stainless steel according to the corrosiveness of the medium to avoid rusting (as stated in Abstract 4).

Standard adaptation: Clearly implement national standards (GB), American standards (ANSI), or other standards (such as abstracts 2 and 4).

Installation and maintenance: When customizing, confirm the installation method (such as flange bolt hole spacing) and reserve maintenance space (such as Summary 3).

If further customization is required, it is recommended to directly contact the manufacturer to provide detailed parameters and obtain accurate quotations and technical solutions.
