To receive the best performance in the angle globe valve, the correct valve must be chosen for the service needed. There are various conditions and factors to take into account to pick the appropriate valve for a particular program. These variables will largely be dictated by service requirements and essential materials of construction.
When considering service conditions, the very first step is identifying which sort of medium will be managed. Different angle globe valve designs are much better suited to liquid, while others are favored for gasoline. If it’s a liquid, it’s important to ascertain whether or not it will contain any solid particulate matter. It is also important to notice whether the media will remain liquid throughout the flow or if it is going to vaporize and be gas along the way.
A Brief Introduction to Control Valves
Another factor to consider is exactly what the pressure and temperature will be throughout the treatment system. This will not only dictate the correct kind about but also what substance the valve should be constructed from. For example, in extremely high temperatures, it may be required to utilize ceramics or refractory metals. At very low temperatures, bronze or stainless steel may be required. The broadest choice of construction materials falls from the intermediate selection. This ranges from 150 to 1000 degrees Fahrenheit. The substances used within this temperature range include carbon steel, cast iron, PVC plastic, and bronze.
Along with considering the primary use of the angle globe valve, it is also important to consider additional factors that might affect the basic material choice. These variables include any necessary corrosion resistance requirements, thermal shock limits, physical shock limits, and possible fire hazards. In most cases, these factors can be addressed either through the initial building material in addition to trim materials.
