Valve Casting

Valve Castings

  The valve is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cutoff, regulation, throttling, check, split or overflow relief. Valve castings are control components in pipeline fluid delivery systems. They come in a wide variety of sizes and sizes. Valve castings are widely used in chemical, petrochemical, petroleum, paper, mining, electric power, liquefied petroleum gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronics industry, urban construction and other fields.

Our foundry is the reliable manufacturer and supplier for valve manufacturers all over the world. We can make all kinds of cast valve components for check valve, butterfly valve, ball valve, gate valve, control valve, globe valve, plug valve, ect. As a valve parts producer, we are professional in making all kinds of valve components including cast valve body, cast valve disc, cast valve bonnet, cast valve flange, cast valve flange and other valve component castings.

As per the material specification and dimensions of valve casting parts, we can make them in different casting process:

Sand Casting: Also a casting process for valve casting parts. Sand casting is suitable for both steel and iron valve castings. Compare with lost foam and lost wax castings, it is more suitable to make larger valve components, so normally, we will need to leave more machining allowance for further machining operation. The max weight we can cast is around 2 tons per piece.

Lost Wax Casting: Is able to make cast steel valve components, like carbon steel, stainless steel, and other cast steel alloys. Lost wax casting is a precision casting method for valve components, so we can achieve good dimensions and tolerances, smoother surface. Stainless steel valve casting parts are widely used in silical sol casting process, which is another lost wax method. We can use this casting process for butterfly valves, ball valves, ect.

Lost Foam Casting: This casting method is more suitable for making precison cast iron valve parts, which can also get good surface finish and sizes, such net shape or near net shape valve castings will need no machining or just little machining allowance.

We believe that Your drawing + our technology = Satisfactory product

Capabilities to supply valve castings

To supply finished valve casting parts, we have machining equipments as well (NC lathe, CNC, boring machine, drilling machine, ect) for different machining requirements. Besides, we also have hydraulic testing capability to ensure workable valve castings.

For large dimensions valve casting parts, to avoid casting defects, it is necessary to do magnetic particle testing and ultrasonic testing after casting.

In conclusion, you can enjoy lots of benefits to purchase valve casting parts from our foundry, like wide material selection, multiple casting methods, machining service, and so on. Once cooperating with us, you will feel lucky to cooperate with such a good supplier for our high quality and competitive prices. Even if you would like to source forged valve components, do not worry, we can also provide you forged valve parts from our another forging company. Just pls contact us once you have demands of valve components.
