The 2040 digital position indicator uses a colored light signal, visible from a distance, to show the open or closed position of a valve. Four different color signals are used: open and closed by yellow and green. At the…
Introduced last month, these two intrinsically safe solenoid valves (photo) have Ex ia IIC T6 certification. The solenoid operators are designed for use on the 327 range of direct-operated solenoid valves, and are available in epoxy-coated aluminum or stainless steel.…
A new agitator-blade design for this company’s Double Planetary Mixer features two identical rectangular stirrers with upward rake fingers. Designed to rotate on their own axes, while also orbiting the mixing vessel on a common axis, the stirrers are ideal…
Coolant circuits must dissipate heat from applications such as welding or power-electronics installations. This requires high flowrates within a compact space. This company has extended its Liquidline by designing two energy-optimized coolant connections that exceed the flowrates of previous Liquidline…
Dickow Pump No cooling water needed for these hot-water pumps This company offers a wide range of hot-water pumps for temperatures up to 530°F and design pressures up to 1,160 psi. Due to high vapor pressures, standard mechanical seals cannot…
The Type 3738 electonic valve-position monitor can be used with on/off valves across a wide range of applications, and enables valve-position monitors to be configured at the push of a button. The device features a contactless, magnetoresistive sensor system that…
To realize the best possible thermal efficiency, gas turbines should be integrated into chemical process industries (CPI) plants, but doing so can be difficult and requires special consideration. Specifically, in some CPI units, while the turbine’s shaft is driving an…
Microwave irradiation of graphite has been shown to produce graphene oxide with 90% yield by the research group of professor Yuta Nishina, Research Core for Interdisciplinary Sciences, Okayama University (Okayama, www.tt.vbl.okayama-u.ac.jp/archives/809). The yield is not only nearly twice that obtained…
Conventional methanation — the reaction of CO and H2 (synthesis gas) to form methane — has recently become important as a way to produce substitute natural gas (SNG) from gasified coal in regions of the world where natural gas is…
A team from Monash University (Melbourne, Australia; www.monash.edu.au) has prepared graphene monoliths with a cork-like hierarchical structure, exhibiting ultra-low density, superelasticity, good electrical conductivity and high efficiency of energy absorption. The ability to maintain structural integrity upon large deformation is…
