A fluid union includes a rotatable member with an axis to rotate about, a non-rotatable member, and an actuating member disposed between the rotatable member and the non-rotatable member. The actuating member is moveable along the axis between an engaged position and a non-engaged position and the actuating member is biased towards the non-rotatable member.

Rotating fluid union

Valve assemblies and methods of designing valve assemblies having a valve ball, an upper seat, and a lower seat. When fluid pressure is applied to the valve ball, the valve ball will float in the axial direction between an upper position, a neutral position, and a lower position in response to fluid pressure. The valve assembly may be made suitable for internal blowout preventers.
