You might be building a simple piping system to help you move your materials through processes. A complex multi-system with automated controls, monitoring, and more flow control is most likely an essential part of your project.
Stainless steel valves are most likely to help with flow control. However, to ensure safe and long-lasting performance or prevent typical hazards. Choosing the correct valve, such as figuring out control valve vs gate valve among available designs, is essential. In this article, we will discuss Ball and Needle Valves and their differences.
Ball valves acquire their name from their design. At the center of the valve is a ball with a channel running through it. By rotating the ball 90 degrees, you can expose this channel to the flow stream, generating an open or closed state. Moreover, the ball valve’s short throw makes it a good choice for controlling flow in that specific position has full open or closed conditions, which are common when fast switching between states is needed.
Additionally, the design permits an extraordinary airtight seal. Since the valve seat is self-cleaning and there are few components within the valve, cleaning and maintenance requirements are minimal.
Ball Valves have two types. One is called Floating Ball, and the other is called Trunnion Valves, which describes how the ball is positioned within the valve. Types can be subdivided into body styles and configurations.
The Floating Ball valves are considered the most popular valve. This type of valve is not fastened to the stem, allowing for much freedom. The upstream pressure helps create the seal by pressing the ball onto the downstream or rear seat.
Unlike the Floating Ball, this kind of valve is designed with a pin to prevent the ball from dislodging. This design applies to systems with high velocity. The ball is well-supported by shafts or posts on the opposite sides. The shaft may or may not be a part of the ball. However, trunnion valves reduce friction between the ball and the seal.
