3PC Forged Steel Ball Valve

KOSEN 3PC Forged Steel Floating Ball Valves has a good sealing performance, however, we need to consider whether the outlet side seat could bear the working pressure as the movable ball would nearly pass all the medium pressure to the seat. For this reason, the floating structure is generally for middle & low pressure working pressure.
