Parker Hannifin Corp. has introduced two new technologies: a compressed natural gas (CNG) vehicle gas regulator system for medium- and heavy-duty vehicles, and fuel-dispensing solutions for high-flow, high-cycle CNG applications.
The regulator system, available in a machined or cast body, offers stable, reduced-pressure delivery and control of natural gas throughout extreme engine and environmental operating conditions, the company explains.
Integrated internal regulator components eliminate fuel line failures due to freezing, dampen flow-induced vibration, reduce drop at high flow and extend cycle life. It consists of an integrated filter, inlet solenoid valve and heat exchanger – ideal for six- to 15-liter engines.
The dispensing solutions feature what the company calls the only entirely integrated fuel dispenser in the industry – the Parker Industrial Bulk CNG dispenser, which includes 4x burst pressure rating components, ball valves with a cycle life of 100,000 full cycles and an integrated system design resulting in 15% to 20% fewer leak paths.
‘The Parker CNG dispenser was designed with safety as a top priority and uses a specially designed frame, series of unique protective sensors, breakaway couplings and hose disconnects to eliminate the risk of mechanical or user malfunctions,’ says Anil Raina, engineering manager at Parker Veriflo/Instrumentation Group.
