Pressure converter valve

A pressure converter valve comprising:

• a solid body;
• a pair of first inlet ports and a pair of first outlet ports formed in said solid body;
• said body including a plurality of interconnected bores;
• a plurality of unidirectional fluid flow devices disposed within certain of said bores to form fluid flow paths between said first inlet and said outlet ports such that fluid flows in a first direction from one of said first outlet ports and in a second opposed direction through said other first outlet port regardless of the direction of fluid flow through said first inlet ports;
• means for mounting a fluid control valve having inlet and outlet ports on said body of said pressure converter valve in fluid communication with the bores therein, the mounting means including first outlet ports in said body of said pressure converter valve being arranged to mate with said inlet ports of said fluid control valve;
• said body having a pair of second inlet ports disposed adjacent to said pair of first outlet ports on said body and arranged to mate with said outlet ports of said fluid control valve;
• and
• said body having a pair of second outlet ports respectively disposed in fluid flow communication with said second pair of inlet ports on said body and adapted to be connected to a fluid operated device controlled by said fluid control valve.
