Disc Floating Ball Valve
Introduction
The Disc Floating Ball Valve is a quarter-turn gate valve with a float + disc sealing structure. The float is fixed by the valve seat, and a seal is achieved when the float presses against the disc valve seat under pressure.
Advantages
Valve disc type seat structure
The valve disc provides uniform sealing force, reduces wear, and extends service life.
Reliable shut-off performance
The Disc Floating Ball Valve achieve zero leakage for water, oil, gas, and chemical fluids.
