Parker Hannifin Corporation, a global leader in motion and control technologies, has introduced the Parker’s Veriflo Division FM80 Fuel Regulation Module, described as the industry’s only fully integrated CNG (compressed natural gas) flow control and regulation system for medium- and heavy-duty vehicles with 5- to 12-liter engines, at this year’s ACT Expo in Dallas TX. Parker’s advanced FM80 withstands extreme variations in temperature, flow, vibration, supply pressure, and gas composition, setting a new standard in CNG fuel handling.
Most current gas handling systems are typically comprised of a rubber-like diaphragm regulator, filter, sensors and solenoid plumbed together with a multitude of fittings. Instead, Parker’s FM80 features an advanced FM80 metal piston-style regulator, coalescent filters, pressure sensors, a lock-off solenoid valve, heat exchanger, and low-pressure relief valve, all in one compact body. The system offers customizable levels of integration and more configuration options than comparable products. The complete CNG fuel system exceeds industry standards for leakage and safety. It has been tested on a variety of engines and meets the flow and regulation specifications of all leading OEMs with CNG options.
According to Madhukar Puniani, Business Development Manager (Natural Gas Systems), Parker Veriflo Division, “Aside from being the only complete system solution on the market, the Parker FM80 Fuel Regulation Module offers several breakthrough features to improve performance and vehicle uptime. Incorporation of a larger oil sump means longer times between filter drains, helping increase driver productivity and asset utilization. Innovative technology prevents freezing problems in the winter and eliminates leakage of gas into coolant from wear of soft diaphragms and seals over time.”
The FM80 was engineered for medium- to heavy-duty vehicles like delivery and day cab trucks, cement trucks, school and transit buses, and waste refuse/recycling vehicles. Optimized for advanced fuel handling performance in 5- to 12-liter engines, Veriflo’s 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. The manifold design of the regulator system reduces the chance of fuel line pressure increase due to reduced volume of fuel between the solenoid valve and regulator seals. In addition to the FM80, Parker offers multiple fuel module options for system integrators and OEMs.
The FM80 is designed to achieve the highest nominal flow rate (175 lb/hr / 80 kg/hr) in the industry and the lowest low-pressure operating parameter (250 psig), which increases the usable range of CNG vehicles by a critical 3-5 percent. Other key features and advantages include:
- integrated heating circuit that uses heated radiator fluid to condition the gas before it enters the engine, offering improved reliability at low temperatures and eliminating fuel line failures due to freezing,
- good response to power demand for better drivability,
- well-dampened piston that reduces flow-induced vibration,
- 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°F to + 248°F (-40°C to +120°C) ambients,
- optional boost pressure augmentation for optimized outlet pressure and performance of turbocharged engines, and
- compact size, offering maximum efficiency in a small space.
According to Tamara Horne, General Manager of Parker Veriflo Division, “As a global company, Parker is committed to providing cutting-edge technologies to reduce the world’s dependence on diesel fuel, which is widely used in medium- and heavy-duty fleet and industrial vehicles. Natural gas is cleaner, more economical, and less toxic to the air and environment than diesel. Parker is proud to be the first manufacturer to offer a fully integrated, high-performance CNG fuel management system in the new Parker FM80 Fuel Regulation Module. It’s the ideal system when performance and productivity of your fleet is critical to your business.”
Parker Veriflo also presented two Veriflo fleet dispensing solutions for high-flow, high-cycle CNG applications at ACT Expo. The Parker XF70 Fast Fill Commercial and Fleet Dispenser, launched at last year’s event, was designed from the ground up to offer the industry’s first NFPA 52 and CSA NGV fully-compliant solution for large fleets. The XF70 is the CNG fleet fueling industry’s first internet-enabled CNG dispenser, using IoT smart technology to manage fueling strategies and maintenance. TF25 Time Fill posts were designed with the industry’s largest waste fleet trucks in mind and are compliant to NFPA, seismic, and wind-load requirements of the lower 48 states.
