The high-precision and dynamic control with the first proportional valve terminal VTEP on the market accelerates production - and at the same time ensures a higher quality of the manufactured products. This enables Festo to make machines and systems more efficient and helps the electronics and semiconductor industries, textile manufacturing, battery production and life sciences, for example, to gain decisive competitive advantages.

Pressure or vacuum? Both!

At less than 120 mm wide, VTEP is the most compact proportional valve terminal on the market for pressure control with 10 working channels. It can be easily integrated for multi-channel applications - in two-, three- or five-channel versions. Pressure and vacuum can be combined in different control ranges.

The directly controlled VTEP uses piezo technology, which makes the pneumatics highly precise, fast and economical with the appropriate control technology. This brings further advantages: the valves are noiseless, wear-free, without particle abrasion or heat generation. The valve terminal is also free of copper, nickel and zinc, making it ideal for battery production and other industrial segments in which these materials are not desired.

Wafers, batteries and more

During wafer production, the variable contact pressure of the individual polishing chambers on the polishing unit is controlled with high precision via Controlled Pneumatics with VTEP. The uniform pressure ensures excellent results over the entire processing surface - even when polishing sensitive wafers. VTEP valve terminals can also be used as pilot valves for media valves. For example, wafers must be precisely wetted with a light-resistant coating during processing (process step: photolithography). A suck-back function controlled by VTEP ensures that no excess lacquer escapes.

The VTEP proportional valve terminal is also suitable for many applications in web control, such as the production of battery foils. VTEP communicates almost in real time and the valves react at lightning speed. In the event of unexpected forces, the perfect timing ensures significantly improved process reliability.

Growing portfolio from Controlled Pneumatics

With Controlled Pneumatics, Festo combines proportional technology, sensors and control algorithms to create a control loop. This technology opens up completely new fields of application for pneumatics in terms of pressure, flow and movement - and also makes conventional production more efficient. Last but not least, the high-precision piezo valves reduce the consumption of compressed air by up to 50 percent, as it can be perfectly metered. This is now very simple: the closed-loop control system can be put into operation by entering just a few parameters thanks to Festo's sophisticated algorithms.

In addition to VTEP, the controlled pneumatics portfolio is constantly evolving for many applications. With the Festo Motion Terminal VTEM, movement, pressure and flow can be individually controlled and activated via motion apps. This digitalizes pneumatics, as the valve functions are controlled via apps. The proportional pressure control valve VEAB, which is often used in medical technology, for example in ventilators, is silent in operation and requires hardly any energy. The VPPI proportional pressure control valve is characterized by the fact that controller presets and pressure curves can be individually adapted.
