Parker Hannifin Corporation has introduced the Parker Veriflo Division FM80 Fuel Regulation Module, a fully integrated CNG (compressed natural gas) flow control and regulation system for medium- and heavy-duty vehicles.

  • Withstands extreme variations in temperature, flow, vibration, supply pressure and gas composition
  • Features advanced FM80 metal piston-style regulator, coalescent filters, pressure sensors, lock-off solenoid valve, heat exchanger, and low-pressure relief valve all in one compact body
  • Offers customizable levels of integration and more configuration options
  • Exceeds industry standards for leakage and safety
  • Meets flow and regulation specifications of all leading OEMs with CNG options
  • Includes several features to improve performance and vehicle uptime
  • Features technology which prevents freezing problems in the winter and eliminates leakage of gas into coolant from wear of soft diaphragms and seals over time 
  • Incorporation of a larger oil sump means longer times between filter drains, helping increase driver productivity and asset utilization
  • Optimized for advanced fuel handling performance in 5- to 12-liter engines
  • Piston-style regulator design offers stable pressure delivery and control of CNG throughout the full range of extreme engine and environmental operating conditions
  • Integrated internal regulator components, with fewer connections, work together to eliminate fuel line failures due to freezing, dampen flow-induced vibration, reduce drop at high flow, and extend cycle life
  • Manifold design of regulator system reduces chance of fuel line pressure increase due to reduced volume of fuel between solenoid valve and regulator seals
  • Achieves high nominal flow rate (175 lbs./hr, 80 kg/hr) and the low low-pressure operating parameter (250 psig), which increases the usable range of CNG vehicles by 3 to 5%
  • Integrated heating circuit uses heated radiator fluid to condition gas before it enters engine, offering improved reliability at low temperatures and eliminating fuel line failures due to freezing
  • Well-dampened piston reduces flow-induced vibration
  • Offers reduced pressure drop
  • 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 to 248 F (-40 to 120 C) temperatures
  • Includes ptional boost pressure augmentation for optimized outlet pressure and performance of turbocharged engines
  • Features compact size, offering maximum efficiency in a small space
