CONTROLLED PNEUMATICS: FOR PRECISION, CONTROL AND LOWER ENERGY USE PRODUCTS HYDRAULICS & PNEUMATICS


Controlled Pneumatics, the rapidly evolving compressed air technology from Festo, is said to be opening up new applications for pneumatics. According to the company, the technology delivers more precision and control than ever, while having the potential to dramatically reduce energy use. This is demonstrated in the VTEP proportional valve terminal which offers high precision, fast response times, and dynamic control. The VTEP provides extremely sensitive pressure control, down to less than 1mbar, ideal for applications such as wafer polishing or patch clamping in life science. In addition, Controlled Pneumatics uses high-precision piezo valves to reduce compressed air consumption by up to 50%. This level of control enables the VTEP to speed-up production while ensuring that manufactured goods are of a higher quality, the company explains. At less than 120mm wide, the VTEP is the most compact proportional


valve terminal for pressure control with 10 independent work channels. There are three versions, with 2-, 3-, and 5-valve positions, which can all be easily integrated for multi-channel applications. Pressure and vacuum can be combined in the control range of -1 up to 6 bar positive pressure. The individual valves can be controlled to control the pressure, block, or exhaust the system pressure. The directly controlled VTEP uses piezo technology which, together with


PROPORTIONAL VALVE WITH PRESSURE COMPENSATION


Bürkert Fluid Control Systems’ new Type 2852 2-way proportional valve with pressure compensation is said to offer high flow rates as well as higher pressure operations compared to equivalent size valves. It can handle oxygen, air, natural gases, and fuel gases. According to the company, the valve is up to 50% smaller than


alternative pressure compensation valves and has a streamlined form which includes direct inlet pressure control without the requirement for a separate pressure controller. In addition, it delivers high flow rates, with a kVs flow coefficient value of 0.2m³/h, and a pressure range up to 7 bar. The valve design also provides high performance positioning, achieving a repeat accuracy deviation of less than 1%, and response sensitivity deviation lower than 0.1%. Featuring an expansive setting range of over 1:500, the single width design covers the equivalent scale of orifice sizes between 1mm and 3mm. The valve’s compact dimensions and low power


consumption make it well-suited for applications in analytical and medical devices.

the appropriate control technology, makes the pneumatics extremely precise, fast, and economical. Additional benefits include a valve that is quiet, free of wear, has no particle abrasion, and they don’t generate any heat. In addition, the proportional valve terminal is free of copper, nickel, and zinc, making it very suitable for battery production and other industrial segments in which these materials are disruptive. During wafer production, the variable contact pressure of the individual polishing chambers on the polishing unit can be controlled extremely precisely by the VTEP, with the even pressure guaranteeing excellent quality results across the entire processing surface. The VTEP proportional valve terminal is also suitable for many applications in web control, such as the production of battery foils. It communicates over EtherCat in real time.

AM SYSTEM USED FOR HYDRAULIC VALVE PRODUCTION


High-performance hydraulic valve manufacturer, Domin, is using a RenAM 500Q Ultra metal additive manufacturing (AM) system to increase production of its servo proportional hydraulic valves. Domin’s valves are designed to meet the


rigorous demands of industries such as automotive, aerospace and manufacturing. By using metal AM, Domin can create complex geometries with internal features that are not possible with traditional subtractive manufacturing methods, resulting in parts with a good strength- to-weight ratio and reduced waste. The company’s innovative approach, combining AM with high-speed motor control, modern electronics, big data, and connected technology,


24 DESIGN SOLUTIONS OCTOBER 2024 aims to save the hydraulics industry one gigatonne


of CO2e by 2030. The increased capacity provided by the RenAM 500Q Ultra will help Domin maintain low production turnaround times and deliver consistently high-quality products to its growing customer base. The RenAM 500Q Ultra is the latest addition to Renishaw’s RenAM 500 series of laser powder bed fusion (LPBF) systems. It can improve metal AM capability significantly, using Renishaw’s patented TEMPUS technology to reduce build times by up to 50% while maintaining high pat quality.
