How to Choose the Right Type of Brass Ball Valve for Your Project?

Selecting the right brass ball valve for your project involves considering several factors to ensure compatibility, efficiency, and longevity. Here’s a step-by-step guide to help you make an informed choice:

1. Understand Your Application

Identify the Purpose:

- On/Off Control: For simple open/close functions, a two-way ball valve is typically sufficient.

- Flow Direction Control: If you need to divert or mix flows, consider a three-way or four-way ball valve.
