Ball Valve
Frequently asked questions
Common questions about Ball Valve from 3G Electric.
How do I choose between a 2-way and 3-way ball valve?
A 2-way valve handles simple on/off isolation in a single line. A 3-way valve diverts or mixes flow between two paths, so it suits changeover, bypass or blending duties. Confirm the port pattern (L-port or T-port) and whether you need manual or pneumatic actuation before selecting.
Which ball valve connection types are available in this range?
The catalog covers flanged, NPT threaded and sweat connections across 2-way and 3-way bodies. Selection usually follows the existing pipe system and pressure class — flanged for larger lines and easier removal, NPT for smaller threaded assemblies, sweat for copper piping.
What does 3-A certification mean for a ball valve?
3-A certified valves meet sanitary design standards for food, beverage and dairy service, covering materials, surface finish and cleanability. This range includes 3-A certified stainless steel and brass ball valves, including pneumatically actuated L-port and T-port versions for automated hygienic processes.
