Frequently asked questions
Common questions about Ball Valves from 3G Electric.
How do I size a ball valve for my application?
Match the valve's port size to your pipe's nominal diameter, then verify pressure and temperature ratings against your system's operating conditions. For throttling, consider a characterized or V-port ball valve; for on/off service, a standard full-port valve minimizes pressure drop.
Which ball valve materials are best for chemical or corrosive media?
PVC or CPVC ball valves, such as those from ASAHI or HAYWARD, resist many acids and caustics. Stainless steel (316) suits aggressive fluids and high temperatures. Always check chemical compatibility charts for seals and seats — PTFE is common for broad chemical resistance.
Do you stock actuated ball valves for automated systems?
Yes — we carry brass electrically-actuated and carbon steel pneumatically-actuated ball valves. These integrate with PLC or pneumatic control systems for remote or automated flow control. Specify voltage, torque, and fail-safe position when ordering.
