As shown in the drawing, when the valve is in the open position the valve art.4634 will not allow the draining of the fluid, even in case of accidental opening of the drain cock (1). When the valve is in the closed position a bleed hole (2) in the ball allows the operator to drain the valve by opening the drain cock (1).
