Claim 2:
3. The valve assembly of claim 1, wherein
the ball is further configured to move to the open position by the ball support axially translating and in response to a fluid pressure within the control chamber overcoming a bias of the gas charge within the activation chamber,
the main piston is configured to axially translate into the activation chamber in response to the axial transition of the ball support,
a volume within the activation chamber is decreased and a pressure of a compressible gas in the activation chamber is increased in response to the axial translation of the main piston into the activation chamber, and
the fluid passage of the ball aligns with a tool passage within the valve assembly when the ball is in the open position.
