Stainless Steel Casting for Valve Components

Stainless steel casting is the most widely used technique for valve components. Together with pump castings, such valve castings require highly complicated designs and alloys. With silica sol casting process, we are experienced in making different kinds of valve castings in stainless steel.

Material grades for stainless steel valve castings

We meet and exceed our customers’ specifications for exceptional casting finishes, quality and dimensional accuracy. Frequent materials grades of stainless steel valve castings purchased from CFS foundry are: Stainless Steel CF8M/CF8/CF3/CF3M, SS304/SS316.

Our stainless steel valve castings

valve body casting

Valve body: Investment casting valve body is the core part of whole vave and holds all valve components(valve disc,valve bonnet,ect) together. It is what regulator fluid flow through the transmission to determine which gear it goes into. They can be cleaned/rebuilt/replaced and it usually does not cost too much.

Valve disc: Investment casting valve disc is one of most common components, which is applied to butterfly valve.Investment casting valve disc is opening and closing of control medium flow and circulation, playing a vital role in the whole valve structure. It could be operated by valve handle,or through equipments like turbine operation,pneumatic,electric equipment.

Valve bonnet: valve bonnet is a valve component with valve stem seal parts,used to connect or support actuators.Valve bonnet can be a whole with valve body,but also can be separated.There are two fuctions of valve bonnets,one is valve stem position to ensure stem drive switch normally.Another is sealing function,have a certain strength, preventing the internal fluid flow.

Valve gland: Valve gland is one component of the valve assembly. The valve gland is used to cover the valve gate, worked as the sealings.

We could manufacture all type valve castings in stainless steel for different types of valve application (check valve, butterfly valve, gate valve, control valve ,ect) for valve manufacturers or valve castings wholesalers, we would advise which casting process will be more suitable for you according the usage and dimensions.
