Valve is provided with connecting unit whose first shape is suitable for securing control attachment. Connecting unit has at least one connecting member mounted movably relative to body in way of pin axis. During motion of this at least one connecting member, second shape is attained which is suitable for securing the control attachment of second type. Thus, at least two different shapes may be attained due to availability of parts movable in axial direction for securing the attachment of first or second type.
