ABSTRACT:
A pressure converter valve suitable for use in fluid flow systems. The pressure converter valve comprises a solid body having a plurality of interconnected bores formed therein with unidirectional flow devices located within certain of the bores to form parallel flow paths between the inlet and outlet ports of the pressure converter valve such that fluid flows in a first direction through one of the outlet ports and in a second direction through the other of the outlet ports regardless of the direction of fluid flow through the inlet ports. The pressure converter valve is adapted to have an auxiliary fluid control valve mounted thereto in fluid flow communication with the outlet ports of the pressure converter valve and, further, includes fluid flow paths connecting the outlet ports of the auxiliary valve to an auxiliary fluid operated device which is controlled by the auxiliary valve.
