CONTROLS' new compact 2
DM2® Series D valve is the latest
addition to ROSS' press application double valve family. The 100 percent
dynamically monitored valve has complete memory, is control-reliable and
Category-4 rated for press clutch/brake applications.
D products integrate memory, monitoring and air flow functions into two
identical valve elements. In the event of asynchronous valve element movement
during actuation or de-actuation, the DM2
Series D valves will lock out,
resulting in less than 1 percent residual outlet pressure, inhibiting further
operation of the press.
enhanced safety, DM2 Series
D valves were designed so that removing and reapplying air pressure cannot
reset the valve. A variety of fault reset options are provided (remote air
signal, optional integrated electrical/solenoid, or manual), all of which
require overt action per ANSI, EN and many other global regulations.
D family offers patented dirt-tolerant, wear-compensating poppet design which
provides quick response and high flow capacity. To ensure long service life and
sure shifting capability in potentially harsh environments, the valve has Teflon-coated
back-up rings on its pistons (non-lube service standard, inline lubrication acceptable).
valve is base-mounted, available with BSPP or NPT pipe threads and was designed
with inlet and outlet ports on both sides (plugs included for unused ports).
The size 2 valve offers a 3/2 normally closed valve function and is available
in 1/4 or 3/8 inch port sizes.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
