November 5, 2014 - GF Piping Systems announced Pressure Regulating Valves that eliminates elastomers, exterior metal parts and re-torqueing; These valves can be used in a wide range of markets including water treatment, chemical processing, microelectronics, pharmaceutical, life sciences, and solar. Key to the new design is a special piston that eliminates the use of elastomers in the valve, thereby ending particle shedding for improved high purity operation. This is important in demanding applications that require only minimal amounts of particles in the flow stream. In addition to its elastomer-free capability provided by the piston design, high-purity operation is further enhanced via the valve's threaded bonnet, which has no exposed metal bolts. The central housing nut does away with re-torqueing for easier operation and compact design enables installation in limited space. Other outstanding characteristics include its modular system that allows the user to easily adjust the set pressure range and quickly go from reducing to retaining (or vice versa) by simply switching the cartridge.
The initial product introduction includes two different PRV types in five materials - PVC, CPVC, PROGEF Standard PP, SYGEF Standard PVDF, and SYGEF Plus PVDF-HP - in sizes from 3/8" to 2" (DN 10 - DN 50). Standards include ISO 9393 for tightness and EN 12266 for leak rating.
