Abstract
The centres of the control ball and centres of the sealing members are in triangular relation, the centres of the spherical surfaces of said sealing members being below the centre of the control ball. A downward force on the control ball and through its centre causes a rotational force on the sealing members and tightens the engagement of the ends of the passages of the sealing members with the spherical surface of the ball. A stem is keyed to the control ball and extends exteriorly of the housing and is rotatable to align or disalign the flow passage of the control ball with the flow passage of the housing and sealing members. A downward force is maintained on the control ball through its centre to maintain a rotation force on the sealing members.
