VIDEO TRANSCRIPT:

The manufacturing of semiconductors is a complex and specialized process with numerous applications for precision pressure and flow control. One specific device used in semiconductor manufacturing is a residual gas analyzer. In this application, harsh chemicals are pumped into the device, with numerous sensors used to monitor the process.

A semiconductor manufacturer was facing a big challenge with premature pump failure. The harsh media was degrading the bearings inside the pumps. To address this issue, they devised a solution to install a device that would create a nitrogen blanket around the pump bearings—thus preventing the media from damaging the bearings. However, size, weight, and cost made implementing this solution challenging. That’s when they reached out to �ǳ�web for assistance.

We developed a solution that utilized a precision DR-2 mechanical regulator and an analytical valve with a specific orifice inside to create a precision flow controller. Both products were combined in a small manifold, and we calibrated them to ensure every assembly would maintain the nitrogen blanket and protect the pump bearings.

The accuracy of the DR-2 mechanical regulator allowed the customer to choose a smaller, more cost-effective option to control the pressure flowing through the fixed orifice. The result was a precision flow controller that could be controlled with a simple analog signal open and close the valve. �ǳ�web’s ability to precisely tune the controller to the customer’s exact flow requirements solved the problem and created a long-lasting, robust solution.

�ǳ�web has the expertise and value-added solutions to meet your application needs. If you need assistance with a challenging application, please give us a call.

Pneumatic Solutions for Wound Therapy

Applications

The lack of standardized wound therapy methods and care contributes to unnecessarily long treatment and healing times. In addition, these factors contribute to excessively high costs borne by patients and health plans. Various new technologies and discoveries are bringing to patients the ability to work with their doctors to get wounds under control with pneumatics.

Hyperbaric Oyxgen Therapy for Wound Healing (HBO2)
Oxygen is one of the most versatile and powerful agents available to the modern medical device manufacturers. The therapeutic use of oxygen under pressure has been used to assist wound healing for almost 40 years. HBO2 provides pharmacological doses of oxygen to stimulate the tissue, thereby promoting a much quicker healing process.

Negative-Pressure Wound Therapy (NPWT)
Negative-pressure wound therapy is a therapeutic technique using a vacuum source that creates continuous or intermittent negative pressure inside the wound to remove fluid, exudates, and infectious materials to prepare the wound for healing and closure.

�ǳ�web has been successfully partnering with progressive companies in the design and development of innovative pneumatic solutions for both stationary and portable non-invasive topical wound therapy equipment.

�ǳ�web’s miniature valves, actuators, fittings and regulators are ideal for these types of applications, especially with the addition of the Oxygen Clean and Analytical Series Electronic valves.

Product Information

�ǳ�web Analytical Series Electronic Valves

�ǳ�web Minimatic electronic valves are precision-built 2-way or 3-way control valves, utilizing a unique, patented valving principle. There are no sliding parts. Complete poppet travel is a mere 0.007”. As a result, low power consumption, quiet operation, low leak and exceptionally long life are major benefits of this design.

The Analytical Series Valve (A-) combines the proven features of �ǳ�web’s “Mouse” series with the specific needs of the analytical industry, and for applications where cleanliness is especially important. Special materials, manufacturing and assembly processes make this valve perfectly-suited for applications where internal cleanliness, bubble-tight operation, and long life are imperative.
