Parker Hannifin Corporation introduces an advanced CNG (Compressed Natural Gas) Vehicle Gas Regulator System for medium- and heavy-duty vehicles.
- Offers stable, reduced pressure delivery and control of natural gas
- Integrated internal components work together to eliminate fuel line failures due to freezing, dampen flow-induced vibration, reduce drop at high flow, and extend cycle life
- Available in either a machined or cast body
- Offers variety of configuration options
- Consists of an integrated filter, inlet solenoid valve, and heat exchanger all working together to provide advanced fuel-handling performance
- Optimized for 6- to 15-liter engines
- Piston regulator design offers stable pressure delivery and control of CNG throughout the full range of engine and environmental operating conditions
- Manifold design reduces the chance of fuel line pressure increase due to reduced volume of fuel between the solenoid valve and regulator seals
- Achieves high flow rates (165 lb/hr) and lowest low-pressure operating parameter (225 psig), which increases the usable range of CNG vehicles by 10 to 15%
- Integrated heat exchanger uses heated radiator fluid to condition gas before it enters the engine, offering improved reliability at low temperatures and eliminating fuel line failures due to freezing
- Well-dampened piston reduces flow-induced vibration
- Features reduced pressure drop at high flow (75 kg/hr CNG)
- Constrained motion poppet design eliminates lateral loads and seat wear
- Thermal shielding of internal components with PTFE seals isolates gas flow, allowing continuous operation even in extreme -40 F (-40 C) and 135 F (60 C) ambients
- Sealed dome provides for captured vent and boost pressure biasing
- Compact size offers maximum effectiveness in a small space
- Configuration options include a low-pressure relief valve, high- and low-pressure sensors, inlet solenoid valve, and coalescing filter
- Complete system meets or exceeds all industry specifications
- Full line of leak-free, high-efficiency connectors, valves, hoses, fittings and filters to complete the NGV fuel system is available
