What is the difference between a floating ball valve and a trunnion-mounted ball valve?

A floating ball valve has a ball that floats between the seats under pressure, while a trunnion-mounted ball valve has additional mechanical support from trunnions or bearings to withstand higher pressures.

Can floating ball valves be used for both on-off and throttling applications?

Yes, floating ball valves are versatile and can handle both on-off service and moderate throttling applications depending on the design and specifications.

How often should floating ball valves be maintained?

Maintenance schedules depend on operating conditions, but regular inspection, lubrication, and replacement of seals or components as needed can prolong valve life and ensure optimal performance.

Overview

A 3-piece design ball valve is a type of valve that consists of three main components: the body, which is split into three pieces and two end caps.

Key features

Modular Construction: Easy to disassemble for maintenance.
Versatile Design: Allows for different end connections (flanged, threaded, welded).
Durable Materials: Made from high-quality stainless steel or other alloys.
Full Port or Reduced Port: Provides flexibility in flow control.
Blow-out Proof Stem: Enhances valve safety.
Adjustable Packing: Allows for tightening as needed to prevent leaks.
Live-Loaded Stem Seals: Maintains seal integrity over time.
Fire Safe Design: Withstands high temperatures and reduces fire risk.
Anti-Static Device: Prevents static electricity buildup.
Locking Device: Provides security by preventing unauthorized valve operation.
