Material of ball valve body

Ball valve bodies can be cast, forged or machined from any metal you can think of. This is due to the simple and compact design of the ball valve. Applicable metals include:

▶ Non-ferrous metals such as brass, bronze and aluminium
▶ Ferrous metals, including iron, carbon steel and stainless steel
▶ Nickel group, including Hastelloy, Inconel and nickel
▶ Active metals, including titanium, tantalum and zirconium

Ball valves can be made of a variety of plastics and polymers, including PVC, polyethylene and polypropylene, or lined with polymers and plastics, or made of or lined with ceramics such as alumina and zirconia.

The basic design of the American valve body complies with ASME (American Society of Mechanical Engineers) standard B16.34 guideline. These standards determine wall thickness, stress levels and other parameters as well as pressure-temperature relationships for most ferroalloys. The B16.10 guidance also specifies acceptable sizes for many categories of valves, such as industry-specific standards such as API (American Petroleum Institute) Pipeline Valve Standard 6D and API 608 "Metal Ball Valves - Flanged, Threaded and welded Ends". These specifications control size, material and application to ensure valve design is consistent across valve companies. Valve companies that want to enter the global market must comply with ISO (International Organization for Standardization), PED (European Commission Pressure Equipment Directive), CE (PED) and ATEX (Bureau Veritas International Inspection Bureau) standards, as well as many existing standards in countries such as China and Russia. Meeting these standards has become a mandatory requirement for trading with the EU, as have JIS standards in Japan and similar requirements elsewhere.
Yongjia Dalunwei Valve Co., Ltd recommends that you choose carbon steel and stainless steel valve bodies are more cost-effective.
