Proportional valves are available in nine orifice sizes ranging from 0.062 to 0.625. All the valves in this line feature a 250 Hz frequency response and a less than 3% hysteresis. The valves perform at low pressure drops and are for medical, industrial control, and alternative fuel applications. An isolation diaphragm separates the working fluid from the coil and armature. This limits the fluid path exclusively to the poppet area, making these valves suitable for both gases and liquids.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
