HUB AS 5226379 - Caterpillar

The RAPTOR valve is designed to operate within a temperature range of 0 to 85 °C (32 to 185 °F) with a gaseous fuel flow temperature of 0 to 60 °C (32 to 140 °F).The RAPTOR valve should be mounted with the electronic enclosure facing up. It must be mounted onto a flat plate with 0.500-13 size bolts. Consideration must be given to the strength of the mounting plate, in order to support the 43 kg (94 lbs) weight of the RAPTOR valve.The inlet piping of the RAPTOR valve must be in accordance with ANSI/ISA-S75.02 as required for flow metering accuracy. There are two outlet piping solutions possible: * Straight flow* Tee flowThe straight flow solution is used mainly for in-line engines or engines with only one cylinder bank.The tee flow solution is mainly used for V engines or engines with two cylinder banks, two mixers, and two turbos. Close the unused ports with appropriate blocking flanges and gaskets (not delivered with the RAPTOR valve). Plug unused pressure ports (P2 inlet-see outline drawing) with 0.125 NPT pipe plug(s) if applicable. The outlet piping solution for each RAPTOR valve is indicated on the device nameplate.
Leak check all gaseous fuel connections. Leaking gaseous fuel can cause explosion hazards, property damage, or loss of life.
