High Level Pilot Valve - Vacco

VACCOAIRCRAFT PRODUCTSHIGH LEVEL PILOT VALVE1-369-51DESCRIPTIONThe High Level Pilot Valve (HLPV) is used on the F-14fuselage tank. The HLPV uses a plastic foam float to controlthe main pilot valve. The pilot valve is normally open until thefuel level rises enough to raise the float and shut the pilot.The HLPV also has a Pre-check port which allows the HLPVfunction to be verified prior to fueling. When fuel pressure isapplied to the Pre-check port, the bowl will fill and raise thefloat to shut off the main pilot valve within five seconds. Thepilot will also close preventing fuel flow when a negative “g”load is applied.FEATURESOPERATING PARAMETERSOperating Pressure………………80 psig Temperature...............-65 o F to +200 o FProof Pressure…………………..180 psig Temp.
