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.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
The Window Watcher stops the burglar before he does damage or enters the house. House alarm service companies set off alarms and call the service only after the burglar has damaged and entered the house.
