In the early years of process controls, engineers were forced to rely on flow meter tubes and needle valves to control gas flows. Many applications require critical, precise variations of gas control, prompting an ever-growing need for more accurate and repeatable ways of controlling flow and/or pressure of a gas.

The first attempts at electronically controlling gases were electronic units controlled with an analog signal to a board controlling various valves. These units featured greater control when compared to the needle valves, but still had problems with accuracy. Process engineers now have more accurate, reliable solutions with advancements in flow and pressure sensors coupled with new valve technologies.

Digital Mass Flow Controllers feature microprocessor capabilities that allow for either analog or digital input, and provide analog or digital output with memory capability. Accuracy has been dramatically improved over the years—Digital and Analog Mass Flow Controllers now provide process engineers with the immediate benefit of an accuracy and repeatability to meet the demanding applications of today.

exceptionally
long life

�ǳ�web has been working with mass flow control companies for years with its EV/ET series valves. �ǳ�web EV/ET valves are precision-built 2- and 3-way versions utilizing a unique, patented valving principle with no sliding parts. As a result, low power consumption and exceptionally long life are major benefits of this design, making them well-suited for Digital Mass Flow Controllers.

Due to the valve size and poppet movement, EV/ET series valves flow 17 l/pm at 100 psig. A booster can be added with a simple assembly process to bring the flow up to 176 l/pm.

higher flow

�ǳ�web also offers the DV Series, a powerful new valve which is built on the same valving principles as the EV/ET series valves, but is designed to flow more. The DV Series valves flow 100 l/pm at 100 psig and are available in standalone, manifold or cartridge versions.

�ǳ�web provides engineering and application expertise to assist companies in the development of new, innovative solutions for digital mass flow control applications. For more information, call 877.245.6247.

Applications

Ever experience the bone jarring, teeth rattling pounding from riding in a boat? Pounding so abrupt and hard you just know your lumbar spine was hammered closer to your cervical spine? The times when you felt like you needed to say to your friends you had a great time, but in truth you were glad to be back on land? Now, imagine going even faster—hitting the waves even harder, and with more frequency...

Gliding on Waves

greater safety & control

Covering the vast coastlines of our waterways, the military must at times endure the extreme harshness of fast speed and unnerving demands for control. In order to provide greater safety and control, �ǳ�web's value added team, working in concert with Shockwave engineers, has developed a custom engineered system that provides a much safer, smoother ride.

Shockwave Seats, a division of Professional Components, Sidney BC, Canada, has developed products that have been used in numerous markets, including; military and law enforcement, rescue and patrol, racing and performance, cruising and fishing, and much more. According to president David Smith, Professional Components was awarded the single largest shock mitigation seat contract by the United States Coast Guard to supply seats for Homeland Security patrol vessels.

"The Coast Guard wanted a simple solution to enable them to adjust the air shock absorber for varying payloads and sea conditions. We had a rough idea of what we needed and built a crude working prototype. �ǳ�web took the idea and ran with it, and within a short period of time we had the slick, robust version we call the RCC or Ride Control Center.The Coast Guard likes it, and we have enjoyed our working relationship with �ǳ�web."

custom engineered

It is a very straight forward solution. First, the system is pressurized by pumping the stainless steel cylinder the necessary number of times to allow for the weight of the passenger. It is then locked (stowed) in position. From here, it is a matter of personal preference as far as the cushion of the ride is concerned—the easily accessible ride control valve enables the passenger to adjust the amount of air/ how fast the air can pass through the air volume tank. The more air that is allowed to escape, the more cushy the ride.

�ǳ�web's control system includes a stainless steel cylinder, special aluminum manifold, four cartridge stem valves, a ride control valve, mufflers, knobs, and a pressure gauge.

Precision Control for MicroBlasting

Applications

As micro-abrasive blasting becomes more and more sophisticated, manufacturers are continuing to develop equipment for a wider range of intricate processes used in many industries. Some of those industries include medical, precision machining, aerospace, semiconductor and more.

micro blasting

Micro blasting describes the process of delivering micron sized abrasives by means of compressed air or gas to the surface of an object. This process demands a very precise means of control—not only in volume, but in speed, distance from the part, and other variables depending on the base material. Although manufacturers offer many types of blasting machines, most are delivered through a very small nozzle. The orifice of the nozzle will vary depending on the blasting material, but the small nozzle size enables the micro blasting of precision parts for medical pacemakers, texturing surfaces for adhesives, or the cleaning/de burring of very small parts, just to name a few.

controlled delivery

Comco, Inc., located in Burbank, California, recently introduced their AccuFlo micro blaster. Their patented PowderGate valve controls the on/off action of the abrasive material. This control process utilizes Comco's patented Simoom Technology. As applied to AccuFlo, Simoom Technology describes how the modulator, media tank and mixing chamber work together for a controlled delivery of the abrasive.

quality & precision

Housed in the control panel is one of �ǳ�web's Minimatic® stainless steel cylinders, which was designed and built for this particular application. The function of the cylinder in the delivery process is to precisely open and close the PowerGate valve. Working in concert with the distributor and Comco Inc., �ǳ�web's application engineering was able to meet the design criteria and quality needed for this micro blasting process.

Pneumatic Solutions for Oxygen Concentration

Rachel Desenberg — Tue, 22 Apr 2014 17:45:58 +0000

Category:

Applications

Normal atmospheric air consists of only 21% pure Oxygen with the balance being Nitrogen and other gases. For medical patients requiring Oxygen therapy, traditional compressed air or liquid air may not always be available or convenient. For those in need of a more portable solution, Oxygen Concentration devices are available in much smaller, more lightweight designs. A variety of models are offered for stationary applications as well as home and portable use.

oxygen concentration equipment

Oxygen Concentrators draw the ambient air through an intake valve, pass the air through filters to remove contaminants which separates the Oxygen from the Nitrogen, Argon and other contents. By extracting the Oxygen, the concentrator delivers a flow that will typically have a purity of up to 95% Oxygen to the patient. Both continuous and pulse flow operation is available.

This technology is especially utilized for personal medical care and travel, airline and military operations, ambulatory equipment, disasters, and more.

innovative solutions

�ǳ�web has been successfully partnering with progressive companies in the design and development of innovate pneumatic solutions for both portable and stationary Oxygen therapy equipment.

�ǳ�web's miniature valves, actuators, fittings and regulators are ideal for these types of applications, especially with the addition of new "DV" Series, as well as the Oxygen Clean and Analytical series electronic valves.
