If the valve is opened, the holes in the ball stay in line with the body inlet allowing contents to pass.The balls are generally made out of several metallics whilst the seats are made from soft materials like Teflon. The combination of materials means the ball valve can operate at temperatures as low as -200 deg C and as high as 500 deg C.Mainly used for air, gases and liquids, ball valves are quick to turn on and off and have a tight sealing with low torque. The only downside to these valves are the lack of throttling properties available. View Full Blog Content...
