Structure features:

1, It is short in face to face dimensions, being 1/4-1/8 times that of traditional flange type check valve.
2, It is impact in volume size and light in weight of about 1/4-1/20 times that of traditional flange type check valve.
3, The disc closes quickly with less water hammer pressure.
4, It is convenient in installation, being available for use on level or vertical pipeline.

5, Flow passage is fluent with flow resistance.
6, It acts sensitively with good sealing effect.
7, Disc travel is short with less impact force caused by valve closing.
8, It is impact in integral structure with nice outline view.
9, It is longer for service life with high reliability.

Special Alloy Casting

On the basis of ordinary carbon steel, an appropriate amount of one or more alloying elements is added to form special alloy steel, such as chromium, tungsten, manganese, nickel and other elements. According to the difference of added elements and appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties can be obtained. The special alloy castings produced by investment casting with these special alloy materials also have corresponding special properties. We can add corresponding special elements according to the specific use requirements of the product to cast Investment Casting Parts with special functions. Because investment casting requires molten material, which makes it easier to add special elements, special alloy parts are particularly suitable for investment casting.

SCZY can customize castings with special functions according to the special requirements of customers. We can not only improve and enhance the properties of castings during the casting process, but also add special elements to the materials to improve and enhance the special properties of castings. It can provide any value-added services after casting.
