Where there is no metal, there is no corrosion. Just like in the new generation of diaphragm valves from GF Piping Systems. Instead of the usual four metal screws, the new diaphragm valve has only a central plastic housing nut. And what is the direct advantage of this? The corrosion-free connection guarantees homogeneous expansion when exposed to temperature variations, which eliminates the need to retighten the screws. This results in uniform surface pressure that guarantees tightness up to 16 bar operating pressure. It began with the wish for something new. Out of this came something new for the market: safer, simpler and more efficient. Georg Fischer Piping Systems is revolutionizing your idea of a diaphragm valve.
Open or closed, automatic or manual: With flicks of the wrist the new diaphragm valve can increase flow or turn everything off completely. The lockable handwheel is a standard feature, the two-coloured position indicator shows the actual position of the diaphragm at a glance. Moreover, at the same time the upper housing section is the interface for a self-adjusting electrical position indicator. All the installation dimensions of the previous model were retained so it is backward compatible.
What is your definition of efficiency? 10, 15 or even 20 percent more? The new generation of diaphragm valves offers 100 percent more flow. That means doubling the flow rate at constant energy consumption. The key lies in the optimized geometry of the valve body. At the same time, the new diaphragm valve has linear flow characteristics and thus guarantees both increased efficiency and constantly stable processes. The minimized dead space also provides maximal hygiene.
