and out of the openings 94 a ball 130 is shown in fig9 and it has a fluid inlet 132 which is in fluid communication with two semi transverse fluid outlets 134 each one having an axis that forms an angle with the axis of the other discharge opening of about eighty degrees with the fluid inlet 132 the fluid outlets form something resembling a y shaped passageway a keyway 136 cooperates as described above with a key to first of all keep the ball 130 oriented in for example a cartridge body and also to transmit torque to the ball 130 to cause it to rotate from a closed position to an open position and back again fluid discharge openings in a cartridge body would be suitably sized shaped and positioned relative to the fluid discharge openings 134 in the ball 130 so that fluid can flow out of the openings 134 and out of the discharge openings in the cartridge this design reduces turbulence inside the ball and would be well suited for high flow rates a ball 140 is shown in fig1 and it has a fluid inlet 142 which is in fluid communication with a transverse fluid outlet 144.
