Introduction

A ball valve is a type of flow control device commonly used in various industrial and residential applications. It features a spherical disc, or “ball,”

with a hole through its center that allows or blocks flow when the valve is rotated. Due to its simple design, reliability, and ease of operation, ball valves have become essential components in many systems, from plumbing to industrial pipelines.

Overview of Ball Valves

Ball valves consist of several key components, including the valve body, the ball, the stem, and the seat. The ball, which is the heart of the valve, is typically made of metal or plastic and is designed to rotate within the valve body.

Depending on the type of ball valve, it may be categorized as full port, which offers minimal flow restriction, or standard port, which slightly reduces flow. Additionally, ball valves can be floating or trunnion mounted, each offering different benefits depending on the application’s needs.

Working Principle

The operation of a ball valve is straightforward. When the valve handle is turned, the ball rotates, aligning the hole in the ball with the flow path, allowing fluid or gas to pass through.

Turning the handle in the opposite direction rotates the ball to block the flow. This mechanism provides a quick and effective way to control flow, making ball valves a popular choice for applications requiring fast shutoff and low leakage.

Applications

Ball valves are widely used across various industries due to their versatility and reliability. In industrial settings, they are commonly found in oil and gas pipelines, water treatment plants, and chemical processing facilities.

Residentially, ball valves are often used in plumbing systems for water supply control. Their ability to handle a wide range of pressures, temperatures, and fluid types makes them ideal for both high-demand industrial applications and everyday household use.
