ABSTRACT:
A valve arrangement is provided which comprises a valve body and a flexible curtain member. The valve body defines at least one fluid flow conduit, and a transverse curtain member track. The flexible curtain member is slidable positioned within the curtain member track, with ends projecting outwardly therefrom. Opposite ends of the curtain member are anchored securely in position, to define a curtain member orientation having opposite roll-cups defined thereby, projecting outwardly from the curtain member track. As a result of the roll-cups, the curtain member can slide between first and second extreme positions, to operate the valve arrangement.
