3PC Forged Steel Ball Valve
Product Description 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...
When the forged steel floating ball valve is used normally, its cover valve seat, spherical valve and seat holder will form soft seal and have reliable sealing performance. When the seat and O-ring are damaged, the seat holder and valve body will be covered with expanded graphite, so as to achieve fire safety. Floating forged ball valve, the valve switch position, valve body and bonnet double cover gasket and O-ring settings, can ensure that in the case of fire, high temperature, shock absorption and uneven opening or closing torque will not cause leakage phenomenon.
