Conoflow Series HPNGV4 Heavy Duty Natural Gas Vehicle Regulator The New HPNGV4 Series CNG Regulator incorporates the same robust design and manufacturing characteristics as the HPNGV2 Series, and offers improvements in value by offering an optional inlet sensor and/or solenoid (high pressure shut-off) integrally mounted into the regulator. Over a decade of service in the most demanding applications has proven the HPNGV Series Regulator is the choice for OEM vehicle, engine and fuel systems. Certified to ECE R110, the HPNGV Regulator is proven to be a safe and reliable pressure control element. Certifications and Approvals pending are for ISO15500, ANSI/AGA NGV3.1 and ARAI Type Approval AIS-037. Standard Specifications Regulated Media: Compressed natural gas Inlet Pressure: 250 to 3600 psig (1.72 MPa to 24.84 MPa) to meet all performance specifications. Nominal Output Pressure Range: Factory preset 45-150 PSIG (0.31-1.03 MPa) Set Point. The typical range of delivery pressure is +15 / -10 psi from specified setting throughout the range of inlet pressure, temperature and flow.

No Sensor Installed - Port Not Plugged. 2. See drawing for electrical connection. 3. Sensor output with 5.0 volt DC Excitement for 5000 psig span. 4. Maximum solenoid wattage: 24 watts. REGULATOR COOLANT BOWL OPTIONS Thermostat No Thermostat Coolant connections are for 3/8” (9.5 mm) ID hose. INTEGRAL PRESSURE RELIEF DEVICE (PRD) OPTIONS 200 PSI (± 40 PSI) PRD 270 PSI (± 60 PSI) PRD 350 PSI (± 60 PSI) PRD 1. A 200 psi PRD is not recommended for regulator output pressures above 120 psig. 2. The regulator PRD is not suitable as a stand alone safety relief valve. Other downstream protection strategies must be employed for a robust system design. PRD CONNECTION OPTIONS PRD Vents to Atmosphere - Standard 1/4” NPT Male Capture Pipe PRD 1/2” Tube Stub PRD If regulator is located in a hazardous location, a PRD capture pipe must be used to route discharge gas to a remote location. OUTPUT PRESSURE SELECTION Output pressure setting (psig). For values less than 100, use 0XX format. Regulator can be factory set from 45 to 150 psig. See next page for ordering example.
