Ball Valves

  • A trunnion ball valve has mechanical anchoring of the ball at the top and the bottom, suitablf ro larger and higher pressure services. To ensure tight sealing at low pressure, high tensile springs force the seats against the ball while at higher pressure, the medium pressure pushes the upstream seat…

  • A floating ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body; it drifts toward to the downstream side and tightly pushes against the seat under the medium pressure to ensure a reliable seal. The floating ball valve is a simple design with good sealing perf…
