FAQ
What is the difference between a high-pressure ball valve and a standard ball valve?
High-pressure ball valves are designed to withstand higher pressures and temperatures than standard ball valves. They are constructed with thicker walls and stronger materials to handle the increased stress.
Can high-pressure ball valves be used for throttling applications?
While ball valves are primarily used for on/off applications, some designs can be used for throttling, but it is generally not recommended for precise flow control. Throttling can lead to increased wear on the valve components and may affect the valve’s sealing performance.
What materials are commonly used for high-pressure ball valves?
Common materials include stainless steel, carbon steel, and various alloys, depending on the specific application and fluid being handled. Stainless steel is often used for its corrosion resistance and high strength, while carbon steel is a more economical option for less demanding applications.
How do I select the right size high-pressure ball valve?
The size of the valve should be selected based on the pipe size and the desired flow rate. It is important to choose a valve that is large enough to handle the required flow rate without excessive pressure drop.
