The check valve types 561 and 562 ring in a new generation of valves, featuring more safety, simplicity and efficiency.

Our engineers focused primarily on two areas in the development of the new check valves: How can we make an established product type even more reliable? And how can we reduce the wear and tear on moving parts and consequently keep maintenance to a minimum? The solution was to completely redesign the inner workings of the valve.

GF Piping Systems developers examined every function and optimized every detail until a much improved valve performance was measured.

The two check valves type 561 and type 562 fit into the most common piping systems worldwide thanks to our comprehensive product range.
