Krones unveils its own series of valves

Friday 12. November 2010 - EvoGuard valves - empirically optimised, innovative components

As of now the EvoGuard family of high-performance valves is available, all of them manufactured in-house. The components have been designed in all commonly used connection variants and with the nominal diameters customarily used in the food and beverage industries, and provide a series of advantages in both daily operation and maintenance routines. Krones is thus assuming responsibility for yet another task category in terms of process technology, and purposefully progressing its single-source vendor strategy.

The paramount requirement for the designers of Krones’ new series of EvoGuard valves was the incorporation of a high-performance seal. The use of leading-edge material technologies for producing the compounds involved in field-proven qualities creates significant advantages for both disk valves and single or double-seat valves. The seal design and the installation space for the seal take due account of its change in volume and the stress it suffers from differing temperatures or in cleaning routines. In addition, meaningful design features have been simplified, like using a standardised model for the disk seal of the double-seat valve, and for the axial and radial seals as well. This precludes the possibility of mistakes when replacing or re-ordering seals.
One standard component of the EvoGuard valves is the welded, maintenance-free actuator, designed for a long useful lifetime. Another special feature is the actuator for the double-seat valves, which enables the valve to be fast-cycled and also reduces compressed-air consumption.
In addition to the seal design and the high-performance actuator unit, The EvoGuard range features extensive and effective measures for enhancing occupational safety. One example is the guard at the link between the valve’s housing and its actuator – all moving parts are thus protected, precluding the possibility of unintended intervention.
Perfection down to the very last detail – that’s the EvoGuard family of valves for food and beverage plants. With this new product family, Krones has proven once again that there is scope for improvement in every element of a process line. The product range will be premiered for the trade public at the Brau Beviale 2010 in Nuremberg.
