    摘要： A valve is in the form of a valve body (10) having a valve inlet (26), a valve outlet (28) and a valve seat (16) disposed between the inlet and the outlet. A valve closure member (12) is movable between a first, closed position in abutment with the valve seat (16) and a second, open position in which it is displaced from the valve seat (16).
    A shaft (70) is pivotally mounted within the valve body (10) and one end is connected to an actuating handle (14), by means of which it is pivotable. An arm (54) is connected to the shaft (70) and to the valve closure member (12), whereby movement of the actuating handle (14) causes opening and closing of the valve.
    The positioning of the pivoting portions of the valve and the spring within the valve body (i.e. in an aperture actually within the material forming the valve body) means that the only item other than the valve closure member in the path of material being discharged is the arm (54), and that when in the open position the valve closure member causes no constriction of the bore.
