Stainless steel investment casting Industrial valve body
The body, or enclosure, of the valve is often the largest component. Material flows through the body between the ports, and all other valve components connect to it. For example, a standard gate valve has three holes: the upstream port, where material flows into the body; the downstream port, where material leaves the body, and another hole on top to connect the bonnet and actuator. Of course, many valves have three or more ports as well, but the basic configuration is similar.
Depending on the type, size and complexity of the valve, valve bodies may be comprised of a single piece or be fabricated from several separate pieces. Modern casting processes that make use of cores allow the addition of complex inner cavities. These processes, including shell mold casting, investment casting and permanent mold casting, are often used for casting valves.
