Conoflow Series LDNGV Light Duty Natural Gas Vehicle Regulator The NEW Light Duty NGV Regulator (LDNGV Regulator) incorporates the same robust design and manufacturing practices as the HPNGV series NGV Regulator, and offers improvements in function and value for smaller engine applications. This regulator provides the market with a Durable, Stable, Predictable and Repeatable regulator for smaller fuel injected NGV engine (to 5.0 liter displacement) applications. Key design features include an integral (and serviceable) 10 micron filter, an optional solenoid valve (high pressure shut-off), an optional inlet pressure sensor, which is matched to the regulator’s performance, compact size, all fluid connections on a single side, an optional bonnet to intake manifold connection, outstanding performance and durability, all in a handsome and easy to install package. Certified to ECE R110, the LNDV 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: 300 to 3600 psig (2.07 to 24.84 Mpa) to meet all performance specifications Outlet Pressure: Factory calibrated per order / Range from 50 to 150 PSIG (0.345 to 1.03 Mpa) Proof Pressure: Minimum 150% of operating pressure Burst Pressure: Minimum 400% of operating pressure Pressure Accuracy: Outlet pressure to be within ±15 psi (0.103 Mpa) of factory calibrated outlet pressure throughout range of flow, inlet pressure and temperature Flow Capacity: 110 lb/hr (50 kg/hr) Filtration: 10 micron, field serviceable element Temperature: -40 to 257 °F (-40 to 125 °C) Application: Fuel injected engines to 5.0 liter displacement (normally aspirated and turbocharged) Connections: Inlet (high pressure) gas: SAE-4, per SAE J1926 Outlet (low pressure) gas: SAE-6, per SAE J1926 PRRV Gas Discharge Port: 3/8-18 NPT Female Engine Coolant Ports: 1/4-18 NPT Female Optional Bonnet: 3/16” (4.8 mm) Hose Barb Optional Solenoid: Amp Superseal 1.5 (2 wire) Optional Sensor: Packard Metripack 150 (3 wire) Mounting: Sides: (2) M10 x 1.5 bolt threads per side Bottom: (3) M8 x 1.25 bolt threads Weight: Refer to the table on page 4 Approvals: ECE R110 Pending: ANSI/AGA NGV3.1 ISO 15500 ARAI Type Approval AIS-037 Ordering Sequence — Select desired option for each category REGULATOR MODEL BREAKDOWN (CED CODE) TEXT POSITION 1 through 5 OPTION CODE LDNGV S C DEFINITION OF CHARACTER Natural Gas Vehicle Fuel Pressure Regulator REGULATOR BONNET OPTIONS Standard Bonnet (Atmospheric pressure reference) Captured Bonnet (3/16” Straight Hose Barb) SENSOR OPTIONS No Sensor (SAE-3 Port will be plugged) Sensor Only - 0.25 to 4.75 Volt Output (Notes 1,2) Sensor Only - 0.50 to 4.50 Volt Output (Notes 1,2) 1. See drawing for electrical connection. 2. Sensor output with 5.0 volt DC excitement for 5000 psi span. SOLENOID OPTIONS No Solenoid Valve (Port will be plugged) Solenoid Only - Normally Closed Lock Off Solenoid 12 Volts DC (Notes 1,2) Solenoid Only - Normally Closed Lock Off Solenoid 24 Volts DC (Notes 1,2) 1. See drawing for electrical connection. 2. Maximum solenoid wattage: 24 watts. PRESSURE REGULATOR RELIEF VALVE (PRRV) OPTIONS 100 psi (0.69 Mpa) Opening Pressure 150 PSI (1.03 Mpa) Opening Pressure 200 PSI (1.38 Mpa) Opening Pressure 250 PSI (1.73 Mpa) Opening Pressure 1. Opening pressure should be at least 50 psi (0.345 MPA) greater than the specified output pressure. 2. The PRRV discharges into a 3/8-18 NPT port. The user may route any gas discharge from the PRRV safely out of the area. OUTPUT PRESSURE SELECTION Regulators can be factory set from 50 to 150 PSIG (0.346 to 1.03 Mpa). For outlet pressure settings less than 100 PSIG, use 0XX format.
