Floating vs Fixed Ball Valves: Key Differences Explained
Compare floating and fixed (trunnion-mounted) ball valves by ball support, sealing mechanism, operating torque, pressure capability, valve size, cost, and application. Floating ball valves provide a simpler and more economical solution for small- to medium-size, low- and medium-pressure pipelines, while fixed ball valves offer lower torque and greater sealing stability for large-diameter, high-pressure oil, gas, power, and process systems.
Floating vs Trunnion Ball Valve: What’s the Difference?
Compare floating and trunnion ball valves by structure, pressure capability, sealing principle, operating torque, size range, applications, cost, and buyer selection requirements.
