Product Name: Valve Component Cast Iron/Cast Steel/Stainless Steel/Copper Alloys Valve Part Valve Disc Model NO.: Valve Disc Trademark: YDSR Transport Package: Wooden Box Specification: 1m*1m*1.2m Origin: China HS Code: 8421299090 Product Description The disc opens, closes or modulates the flow of the fluid. In the case of a gate valve, the gate (wedge) is the disc of the valve.After the body and the bonnet, the disc is the third most important element for the proper performance of a valve. Discs are generally manufactured in forged steel and are often reinforced (hard faced) to enhance the mechanical properties of the base material.The disc can be manufactured by casting or forging steel in a variety of shapes, designs and material grades. It also can be made in plastic, like PTFE. Or rubber and PTFE coated.For specific applications, special material grades with even stronger corrosion resistance are used, such as super austenitic stainless steels (SMO 254), duplex and super duplex steels (F44, F51, F53, F55), and nickel alloys (Inconel, Incoloy, Hastelloy).Company ProfileYing desi Rui Machinery Manufacturing Co., Ltd.
