Prospector poppet valve has been expanded to operate in extremely low temperatures, from –40°C (–40°F) to 60°C (140°F). Its high flow and short stroke result in fast response times. It is available in air pilot or solenoid pilot design in a wide range of voltages....More

Series 319 oil-less, WOB-L piston dc pump and compressor is small and lightweight (5.1 lb/2.3 Kg). Die-cast aluminum components provide strength and durability. It provides up to 150 psi (10.4 bar) of maximum intermittent pressure, and 93% local barometer of maximum vacuum. Corrosion resistant e-coated exterior finish, stainless steel inlet valve, thermally protected motor and inlet filter/exhaust muffler all provide quiet operation. It is available with 12 and 24 Vdc motor and dryer/solenoid....More

To avoid severe vibration and premature failures, rail and truck shipping containers are subjected to vibration testing. However, failures often occurred because testing was originally only done on the X, Y and Z axes. Studies indicated that the pitch, roll and yaw axes simultaneously exert significant forces that can cause premature product efficiencies, normally attributed to design deficiencies....More

In more hydraulic hybrid news this week, Lightning Hybrids LLC (LH) announced that it will retrofit two shuttle buses for the City of Loveland, Colo., with its fuel-efficient hydraulic hybrid system in December and January....More

Railroad cars carry huge loads, typically 250,000 lb. That capacity makes them very economical for long-distance freight transfer. But until the 1950s, moving rail cars very short distances — such as from one track or train to another — was costly and time consuming. The procedure required a conventional switching locomotive, an engineer to operate it, and a switchman to assist. Trackmobile takes advantage of electrohydraulic cartridge valve manifolds and controls to provide stable transfer for railroad car movers....More
