NGV Regulator Application Survey
The intent of this survey is to obtain from you what you like and dislike about the product you are using, what your true needs and wants for a product and supplier are, what you desire for a pressure control solution, and what the economics of that solution should be. The questions below are designed to provide us with open dialogue about how ITT can satisfy product and supplier needs today, tomorrow and in the future.
Bring along sales sheets and/or instruction, operation and maintenance manuals for the HPNGV products.

Application notes for catalog options:
MAP Bias (position 7 in CED code) is used whenever the customer wishes the output pressure to decrease proportional to intake manifold vacuum, and increase with turbo or super charged intake manifold pressure. This feature allows the fuel system calibrator to take advantage of varying pressure to the fuel injection system from the fuel pressure regulator.
The sensor option offers the customer an electrical signal to drive the vehicle’s fuel gauge. Full span is for 5000 psi, and the voltage range for this span is noted on the CED selection code.
The solenoid options for the HPNGV4 allow a safe and functional automatic valve integral to the fuel pressure regulator. This option is desired where a line solenoid is currently used, and offers the value of integrated components and less piping and fitting costs for the customer.
The type of vehicle duty cycle determines which type of coolant bowl should be recommended. For smaller vehicles which have frequent stop and go operation, or extended idle (taxis, etc) a thermostat equipped coolant bowl is suggested. For larger vehicles which need to maximize the heat input to compensate for high or sustained gas flow operation, the high flow coolant bowl is favored.
The PRD connection depends on the mounting location. For small vehicles which mount the regulator on the chassis, away from the engine or sources of ignition, an atmospheric discharge PRD is usually selected. For applications where gas needs to be remotely vented in the event of PRD discharge, a type P or T capture pipe is recommended. These connections permit the vehicle assembler to pipe the connection to a remote location, away from heat or other risk of gas ignition.
The PRD opening pressure is set point and system dependent. For output settings to 110 psig, an A (200 psi) PRD is usually selected. For higher set points, a B (270 psi) PRD is usually selected. For fully hard piped systems that have high inlet pressure fuel injectors, a C (350 psi) PRD may be desired.
The set point is the regulated output pressure at full tank and engine idle condition. There will be some variance in delivery pressure due to flow or inlet (tank) pressure. See the specifications on the previous pages or the sales sheet.
