Type 561/562 Check Valve


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? 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 due to our comprehensive product range.
