ABSTRACT:
Openings and passages are formed in the valve disc to enable the disc to rotate to active positions on either side of a neutral position upon being moved through a relatively small angle of 30 degrees. The valve disc is adapted to be rotated by a pivoted actuator whose motion is amplified to enable the actuator to rotate the valve disc through its 30 degree angle when the actuator is pivoted through an angle of 15 degrees.
