| SPECIAL FEATURES | THIS CARTRIDGE VALVE IS FURNISHED IN (STANDARD) ALUMINUM HOUSING WITH 1/4 NPT CONNECTIONS TO PORTS 1 AND 2; PILOT CONNECTION 1/8 NPT. HOUSING HAS 2 MOUNTING HOLES OF 3/4-16 UNF. IF PILOT PRESSURES FALLS BELOW MINIMUM PRESSURE VALVE ACTS AS A RELIEF VALVE. DETERMINE MINIMUM PRESSURE BY MULTIPLYING MAXIMUM POSSIBLE SYSTEM PRESSURE BY 11, THEN DEVIDE TOTAL BY 26. WHEN PILOT PRESSURE FALLS BELOW THIS NUMBER VALVE WILL FUNCTION AS A PILOT OPERATED RELIEF VALVE. 26:1 PILOT RATIO |
