Diaphragm Valve 5-Series

Available from GF Piping Systems

The new Generation Diaphragm Valve of GF Piping System sets new standards regarding safety, efficiency and simplicity.
Instead of the commonly used four metal screws it has a central union nut - this non-corrosive connection is characterized by homogeneous temperature behavior, an even surface pressure and high pressure rating up to 240PSI (for water use only).
The optimal flow geometry offers double the Cv values. With almost linear flow characteristics this guarantees stable processes.
The weir of the zero-static valve has been moved directly to the pipe wall of the main line. Therefore dead leg was reduced to an absolute minimum and thus the purity was increased at the same time.
Standard equipment like a lockable handwheel, a two-colored indicator and an interface for a self-adjusting limit switch set new standards in terms of user-friendliness.
The Diaphragm Valve Series is available in PVC, CPVC, PP, PVDF, and ABS body materials in sizes ½"-2" (with larger sizes available in the 3 Series). Diaphragms are available in EPDM, PTFE, FPM and NBR. This material range covers practically the entire spectrum of chemicals with which the diaphragm valves can come into contact, optimizing process compatibility. End connections include true union, spigot, flanged and zero static.
