The valve is assembled of the ball (1), the housing (2), the cage (3), a sealing ring (4), a control element (5) with an operating handle (6), and a valve lock (9). The cage (3) is moved by the control element (5) determining the direction of flow. The motion of the ball (1) is limited by a stop located at one side and the valve lock (9) at the opposite side. The handle (6) can be rotated clockwise and anti-clockwise, facilitating a sucking or a pressing action.
