Engineering now offers a miniature,
motor controlled needle valve. The
MNV-1010-303 is ideal for applications which require precise flow or pressure
control in a limited space. This motor controlled needle valve offers excellent
control due to a high reduction drive mechanism and low angle valve
needle. The valve is suitable for control of flow rates or pressures
and in operation remains stable even when subjected to wide temperature
fluctuations. Manufactured in corrosion resistant 303 stainless steel, a variety of seal materials and weighing only
32 gm the MNV-1010-303 sets an industry
standard for miniature precision control valves. The MNV-1010-303
miniature motorized needle valve is unique due to its small size, precise
metering control and O-ring seal construction. With an installed height
just over 2 Â½ inch the MNV-1010-303 aids designers where space is
limited. The MNV-1010-303 has a valve orifice of .030 inches, high
resolution gear drive and highly tapered valve needle for tight control of
demanding flow and pressure applications. Standard O-ring materials are
Nitrile, (Buna-N), Viton, EPDM and Silicone. Other seal materials are available
upon request. In the future, the MNV-1010-303 will be offered with a built in
controller to allow discrete control of flow rates and pressures. The MNV-1010-303
is unique in the fluid power industry because of its operating pressures,
accurate metering and resistance to aggressive fluids. This valve is capable of
operating with inlet pressure up to 500 psi. The MNV-1010-303 has superior
stability in operation due to its temperature compensating design. The valve remains stable during
temperature fluctuations because the internal components are designed to
negate the effects of temperature changes and are fabricated from the same
material. The MNV-1010-303 is normally constructed of 303 stainless steel but
is also available in 316 stainless steel for even greater corrosion resistance.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
