Ball valves are essential components in process systems, widely recognized for their efficiency in controlling flow and providing shut-off capabilities. In this guide, we explore the P&ID symbol for ball valves, their applications, and how they fit into engineering workflows.
The ball valve is represented in P&IDs with a distinct symbol that conveys its operational characteristics. Below is the standard representation:
| Symbol | Name | Description |
|---|---|---|
 | Ball Valve | A valve that uses a spherical disc to start or stop fluid flow. |
 | 3-way Ball Valve | A valve that uses a spherical disc to control a 3-way flow. |
 | Angle Ball Valve | A valve that uses a spherical disc to control an angular flow. |
