About Kefeng

stablished in Shanghai, China in 2003, Shanghai Kefeng has been a leading provider of valve parts & high alloy materials. Kefeng

specializes in producing and machining various valve parts such as valve ball, valve seat, valve stem and centrifugal casting alloy tube and ring. The expertise and know-how acquired over the years coupled with the continued investments in development of high alloy applications, have made Kefeng become one of the best-known manufacturers in producing corrosion resistant and heat resistant alloy valve parts in China.

Kefeng is a specialized valve parts machining center. We are able to machine valve parts according to customers’ drawings and inspect dimensions with a high precision. Equipped with fully automated and advanced machining facilities, we are able to supply float ball, trunnion ball, three way ball, L type ball, T type ball, V type ball, long stem ball, metal seated ball & seat ring and other valve parts in size ranging from 1/2 inch to 24 inches. The plentiful experiences in handling with high alloy products, has enabled us to avoid the problems of sticking and fracture in process of machining high alloy material. To keep our fully machined products perfectly meet the requirements of the drawing, the CMM probe and specialized ball roundness tester are adopted in the plant.

Centrifugal Casting Option

Acc. to PED 97/23/EC Kefeng Specialize in centrifugal casting for Duplex, Monel, Inconel, Incoloy, Stellite and other high alloy material.

Centrifugal Casting is a Casting process using a metal die which spins at high speed. Once the molten metal is in the die, the centrifugal force shapes the solidifying steel to the structure of the mould.

1. Special Casting.

3. Cost saving.The machining margin of blank Ball and Seat will be dramatically reduced by using centrifugal casting compared to forging. As well, it is a much more flexible and economical way for buyers when they require some small quantity procurement scheme.

Centrifugal casting is an excellent option for handling with spherical and ring-shaped components in high alloy and nickel base alloy which are difficult to forge within a narrow forgeable temperature.

2. Alternatives to shape sphere and ring.

4. Superior Performance. The centrifugal force increases feeding during solidifi-cation and improve the density of the casting. There-fore the centrifugal casting has an excellent mechanical property.
