Safe maintenance & commissioning
LoTo for GEA Hygienic mixproof valves
LoTo solutions available for all hygienic seat valves ensure a safe maintenance & commissioning of process plants. Use an easy-to-apply AIR LOCK to cut off the control air connection. Or replace the feedback system with a sturdy DISK LOCK to safely block valve action.
