Technopolymer-based pneumatics

16 October 2008

Festo has introduced a range of products including; air preparation units, compact and ISO cylinders, one-way flow control valves and a series of solenoid-operated valves and valve terminals. All of these products have significant cost advantages over their traditional counterparts.

Festo’s DSNUP series of pneumatic cylinders, for example, feature technopolymer end caps, stainless steel piston rods and aluminium barrels, and have a list price that is 30% lower than their interchangeable all-metal DSNU counterparts. Available with piston diameters of 16, 20 and 25 mm, the DSNUP cylinders feature ISO swivel mounting and threaded end and bearing caps.

Festo has also launched a series of technopolymer-based valves, available as individual components, as well as fully assembled and tested valve manifolds. The VB12 valves feature a body moulded entirely from IXEF 1022 glass-filled polyamide, resulting in a very cost-effective, low weight design. Complementing the existing 20 mm wide bodied range, the valves accommodate air flow rates from 200 to 1000 litres per minute. Festo performed extensive analysis of the valves to determine the optimum design – it was important that the chosen technopolymer provided a similar modulus of rigidity to metal, to ensure good leakage values and to prevent any misalignment of embedded contacts.
