A high pressure ball valve, the ball valve being tiltable under pressure into tight sealing engagement with a sealing ring at the outlet of the valve body. A joint is formed between the spindle and the ball to allow the tilting action of the ball, while still providing low-torque turning of the spindle. A parallelepiped-shaped joint portion is formed on the bottom of the spindle and is loosely received between two bearing blocks on the ball valve so that small amount of loss motion is provided between the spindle and ball valve. |
