Diaphragm valve, 514

GF valves type 514 diaphragm valve has solvent cement sockets, BS and double the flow rate, compared to it’s predecessor.

The central plastic housing nut instead of the usual four metal screws is a corrosion-free connection. This guarantees homogeneous expansion when exposed to temperature variations, which eliminates the need to retighten the screws. The resulting uniform surface pressure guarantees tightness up to 16 bar operating pressure. At the same time, the diaphragm valve has linear flow characteristics and thus guarantees increased efficiency and constantly stable processes. The minimized dead space also provides maximal hygiene.

The lockable hand wheel is a standard feature and the two-coloured position indicator shows the actual position of the diaphragm at a glance. In normal operation the lock mechanism disappears in the handwheel, so that the ergonomics are not impeded.

GF valves have ensure the installation length is identical to the length in the previous model – this makes for problem-free backward-compatibility
