A METAL SOLENOID MANOSTAT. USED ON CIVILIAN COMMERCIAL AIRCRAFT. NON-ELECTRONIC. MAINLY CONSISTS OF: A THERMOSTAT ASSEMBLY. A SOLENOID ASSEMBLY. A NON-RETURN ASSEMBLY. INSTALLED IN THE PRESSURE CONTROL AND LIMITATION SECTION OF THE ENGINE BLEED SYSTEM. IT CAUSES THE FORMER TO CLOSE, WHICH IN TURN LIMITS THE PRESSURE DELIVERED BY THE AIR BLEED SYSTEM. TRIGGERING POINT 235/270 DEGREES C. IT CONTINUOUSLY SENSES THE TEMPERATURE OF THE AIR DELIVERED DOWNSTREAM (OF THE) PRECOOLER HEAT EXCHANGER OF THE BLEED AIR SYSTEM, AND MONITORS THE DIFFERENTIAL PRESSURE BETWEEN THE UPSTREAM OF THE BLEED PRESSURE REGULATING VALVE, AND THE DOWNSTREAM SIDE OF (THE) PRECOOLER. IT LIMITS THE AIR DELIVERY THROUGH THE BLEED AIR SYSTEM BY CONTROLING THE CLOSING OF THE BLEED PRESSURE REGULATING VALVE PNEUMATICALLY. WEIGHT 1.25 TO 1.3 LBS (0.57 TO 0.59 KG). SOLENOID ELECTRICAL POWER SUPPLY 17 TO 30 VDC.
