Threaded ball valve

1. Product Overview

Threaded ball valves use a spherical ball with a through-hole to control flow. When the hole aligns with the pipeline, the valve is fully open; when the handle is turned 90°, the hole is perpendicular, and the valve is fully closed. This type of valve offers the highest sealing performance and durability among threaded connections.

3. Key Advantages for Fuel Systems

Why customers often prefer ball valves over globe valves:

• Instant shut-off: In fuel fire emergencies, the lever closes the valve in just 1 second—much faster than turning a globe valve handwheel.
• Maximum flow capacity: When open, the ball bore matches the pipe diameter, allowing fuel to pass without restriction or pump pressure loss.
• Full-port sealing: Ball design tightly fits PTFE gaskets, ensuring zero leakage even with volatile solvents.
• Safety lock feature: Many stainless steel ball valves include a lock hole on the lever to prevent unauthorized operation in fuel depots.

4. Common Types

• 2-piece stainless steel ball valve (2-PC): Most popular, high pressure resistance, cost-effective.
• 3-piece stainless steel ball valve (3-PC): Center body can be removed to replace gaskets without disconnecting pipe ends—ideal for fixed fuel systems requiring maintenance.

5. Practical Applications

• Fuel stations and tanker trucks: Installed at discharge and vapor recovery points.
• Generator fuel supply systems: Controls fuel flow from storage tanks to engines.
• Chemical plants: Used for dispensing solvents, alcohols, and lubricants.

6. Customer Advisory Notes

• Handle material: For outdoor fuel environments, choose stainless steel handles coated with vinyl to prevent rust and ensure non-slip grip.
• Material choice: Always recommend stainless steel 304 to keep fuel clean and avoid rust particles contaminating engines.
