Festo's VEAA proportionally controls pressures up to 10 bar with a flow of 7 liters/minute. The VEAB proportionally controls pressures up to 6 bar with a higher flow rate up to 20 liters/minute.
Festo Canada’s new VEAA and VEAB piezo valves use very little energy, generating virtually no heat, which helps qualify them as intrinsically safe for use in volatile or explosive environments. VEAA and VEAB valves combine piezo technology with digital closed loop control for highly precise, consistent, silent operation. Their piezo component, the piezo bender, doesn’t suffer mechanical wear and doesn’t abrade, enabling these 3-way proportional valves to last through a very high number of switching cycles (over 300 million) or set point changes. These new valves from Festo offer precise regulation with high repeat accuracy according to a preset value without fluctuations in the output pressure even with varying air consumption. And both valve types can regulate very small volumes reliably, as well as vacuum and overpressure. Both VEAA and VEAB valves are IP65 rated. VEAA is designed to proportionally control pressures up to 10 bar with a flow of 7 liters/minute. The VEAB can proportionally control pressures up to 6 bar with a higher flow rate up to 20 liters/minute.
