3-PC Body Floating Ball Valve

A floating ball valve is a valve with seats supported ball, that is pushed by upstream pressure towards the downstream seat to ensure sealing. The DN of the floating ball valves range is limited by the capability of the seats material to support the pressure, temperature and weight of the ball. ZAF Valves 3-piece design body structure is available in Cast & Forged steel.
