The AKO manually operated and normally closed Pinch Valves are currently undergoing new production, with a slight change in the casting. Various dimensions of the Pinch Valves are now slightly different to the old type, such as the height and length being shorter. However this will be beneficial within most applications and will work as an advantage.

At some point the old type will become obsolete. The new type manually operated and normally closed Pinch Valves will be painted orange in colour, rather than blue.
