ABSTRACT:
A high-pressure ball valve includes a valve housing with a bore that sealingly receives a cylindrical extension of a valve member. An inlet bore extending to the bore in the valve housing has a bottom seat against which a ball can seal off the inlet bore. The cylindrical extension has a pocket to receive the ball while engaging a stem that extends through a bore in the valve member against a piston of a single-acting piston and cylinder assembly. An outlet bore extends in the valve housing to the bore therein for delivering the fluid passing into the housing from the outlet bore.
