The new DISK LOCK extension for Aseptomag® double-chamber valves type DK makes the GEA portfolio complete, offering the same maximum level of safety as the DISK LOCK systems available for GEA for hygienic valves.

LoTo solutions for our pneumatic seat valves offer you the right choice in any situation. Use an AIR LOCK to cut off the control air connection or replace the feedback system with a DISK LOCK to safely block valve action.

Two dedicated LoTo solutions are selectable for manually operated GEA VESTA® valves. Easy-to apply BELLOW LOCKS block any valve action and keep the valve in either open or closed position.

For more than 100 years, GEA has developed technologies for dairy farming – from the first bucket milking machines to autonomous, digitally connected systems. These innovations have fundamentally transformed dairy farming: away from labor-intensive routines, toward greater productivity, animal welfare and more efficient day-to-day operations.
