The High Cycle Valve is available in angle, inline and internal-only configurations, for ease of integration into new tool designs. High flow port sizes, including NW25, NW40 and NW50, use maximum internal diameters for greater conductance. Internal configurations can be used to integrate directly into the product, such as a load lock chamber, reducing the footprint of new tools. The TIG fusion welded vacuum grade body creates fewer entrapment areas, resulting in less contamination build-up.

The High Cycle Valve is available with an air solenoid for electro-pneumatic control of the valve and a limit switch assembly for remote indication in the open or closed position. In the event of power loss, the valve will automatically close. For leak tight operation, elastomer seals are available in Viton® for typical vacuum operating conditions, or Kalrez or Chemraz for higher temperature conditions and increased chemical resistance.

Easy to follow graphical touch-screens provide total navigational control of the central vacuum system. The setup screen, for example, allows for the naming of loading stations, pumps, purge valves and material sources so you know exactly what is in each hopper and where it is located.

Manifold sharing capabilities allow the 24/128 to reduce the cost for tubing and purge valves and can stage and sequence six vacuum pumps per manifold line. The 24/128 can assign each loading station to any of the pumps connected to the same manifold. When a loader senses demand, the controller triggers the assigned pump to convey. If more than one loader on the manifold needs material simultaneously from different pumps, the controller’s manifold sharing function will then stage the pumps so that they can use the same manifold. The first pump will begin, and when its demand is filled, the next pump will be triggered. The result is a flexible system with minimal tubing and purge valves.

The touchscreen display provides an icon based platform for easy maintenance, operation and troubleshooting. Easy to read diagnostics, operation and installation instructions as well as spare parts information are all available from the touch screen.

The Check Valve Assembly is ideal for full power hydraulic brake systems that must store energy in two separate accumulator circuits. It features high flow capacity up to 11 gallons per minute and a maximum operating pressure of 3,625 PSI. Among the potential applications are split systems with a pressure-compensated pump, and electrohydraulic accumulator charging controlled by a pressure transducer at the unit’s switch port.

Pressure is supplied to two accumulators by the assembly’s inlet port. The inverted shuttle valve isolates the higher pressure of the two accumulator circuits, while directing the lower pressure to the switch port. A check valve prevents pressure at the switch port from leaking back to the inlet port.

By combining the functionality of multiple components into a single housing, the Check Valve Assembly decreases costs and time required for installation. Its design also reduces potential leak points and contains possible failure points for the hydraulic system. The assembly limits check valve leakage to a maximum of 0.25 cubic centimeters per minute at 3,500 PSI.

Broadly speaking, pneumatic tools is to use compressed air driven pneumatic motor and the kinetic energy of external work output of a tool, in accordance with its basic work can be divided into: Rotary (eccentric movable vane). Reciprocating (piston volume ) General pneumatic tool parts mainly by power output, operating some form of conversion, intake and exhaust road section to open and stop the operation control part, tool case and so the main part, of course, the operation of pneumatic tools must also be part of the energy supply, air filters and air pressure conditioning components and tool accessories.

High life, high reliability and self-diagnostic function. 50 million times the life of the cylinder valve and 3000km have been commercialized, but in the textile machinery, there is a high frequency valve life demands more than 100 million times, preferably up to 2 million times. This requirement, the existing elastic seal valve difficult to achieve, which makes sealing gap to regain attention. U.S. Numatics (Numatics) companies have a valve, with gap sealing, ventilation valve in the valve body was later suspended state, the formation of friction-free movement, as well as from the dust-proof function, valve life can be more than 200 million times Although this is an old product, or worth learning.

Most of pneumatic fittings for automated production line, component failures often affect the entire line of operation, the production line of a sudden stop, causing serious damage, for which the work of the pneumatic fittings with high reliability requirements. Requirements of a chemical company in Jiangsu supply of the life of pneumatic fittings in the set is absolutely reliable, due regardless of whether they can continue to use, full replacement. Here also proposed various components life balance, and other so-called life design. Sometimes in order to ensure reliable and had to sacrifice life indicators, therefore, pneumatic system of self-diagnostic function that the agenda, the additional life expectancy of such self-diagnosis function components and systems under development.

With mechanical devices with multiple functions, an increasing number of connection not only increases the installation and maintenance workload, and also easily fail and affect reliability, so wire system improvements also Wei pneumatic fittings and systems designers of the pie.

Many of Use pneumatic fittings, such as rolling mills, textile production line and other, during working hours can not the quality pneumatic fittings interrupted otherwise caused enormous losses to pneumatic fittings of the operational reliability, therefore it is very important. In sailing ships, and use a lot of pneumatic fittings, but able to expand into the field of pneumatic fittings factory in this small, because of its pneumatic fittings particularly high reliability requirements, must be certified by the International Machinery.

To high-speed, high frequency, high response, high life direction. In order to improve the productivity of production equipment, improve the implementation of the components of the operating speed is imperative. Our work rate cylinder is generally 0.5m / s less. According to Japanese experts predict that five years later most of the cylinder will operate at speeds up to 1 ~ 2m / s, and some required up to 5m / s. Work to improve the speed of the cylinder, requires not only improve the quality of the cylinder, but also the corresponding improvement of the structure, such as hydraulic shock absorbers to configure the device to increase the buffering effects. Valve response time less than 10ms, life expectancy increased to 50 million times. The United States has a clearance seal valve, as suspended in the valve spool body, do not touch each other, without lubrication, the life of up to 200 million times.

Widespread use of oil-free lubrication technology, meet certain specific requirements. Because of environmental pollution as well as electronic, medical, food and other industries of the requirements, Huanjing not allowed in there is oil, so no air oil lubrication is the developing trend at the same time no oil lubrication can be simplify the system. Pneumatic fittings is very important.Lubricator European market is already out of the product, generally done without oil lubrication. In addition, in order to meet certain special requirements.

Categorizing linear actuators is not entirely straightforward because many categories overlap.  The “motive power” category can be any type of power source, rotary motor or linear motor powered.  Linear motor solutions are much more commonplace in linear actuators today due to declining costs for this technology choice.  But in a linear motor based actuator, the linear motor is both the motive power and the mechanical transmission at the same time.

Categorizing linear actuators by their mechanical transmission style is another approach.  The most common categories are screw type, belt and linear motor.   But the motive power for a screw based actuator could be a stepping motor or a servo motor.  The stepping motor is predominant because of it’s suitability for positioning, but it may be underpowered for some applications where a servo is needed.   So the linear actuator transmission category can have overlaps because of the different motor types that are used in conjuncion with it.

Price seems to be one means of eliminating the ambiguity.  Stepping motor and lead screw combinations are popular because they are economical and maintaining 0.001″ accuracy is very easy.   Linear motor systems are capable of .5 micron accuracy with little or no friction, acceleration and speed that is incredible, but generally the higher performance comes at a higher price.

But in the end, the selection process is best guided by the criteria of the application.  The list is, thankfully, short.  Load weight or force that must be generated, speed, accuracy and life expectancy or number of cycles of operation.  This last is probably the key determinant in system selection.  Long life or high cycling goals lead to linear motors actuators with little or no friction. You have to familiarize yourself with the overall field because the tendency of confusing the technology and the application needs.

At the recent Semicon gathering of manufacturers involved in semiconductor manufacturing, a lot of attention is given to the mechatronic content of machinery.  And as far as I have been able to determine from many different market research projects, semiconductor manufacturing is one of, if not, the largest market for mechatronics every.   So it’s also not a surprise that a lot of vendors come to the Semicon show with their latest and greatest product offerings.

Among the most interesting, Nanomotion continues to extend the reach of piezoelectric linear motors, yet another technology choice within the linear actuator sphere.  Piezo motors have only one moving part, and meet the high precision, high reliability criteria.  With increasing usage, there has been decreasing cost for this unique solution, along with superior position feedback technology and excellent packaging for space constrained applications.

In addition, IKO has released a number of new linear actuator assemblies, both screw driven and linear motor driven.  They are also showing a number of unique 2-axis configurations one of which is the thickness of a tape reel and is targeted to unloading parts for electronic pick and place machinery.

Brilliant examples of manufacturers continuing to integrate mechatronic technology to make it more convenient for the customer.
