GF Piping Systems’ Pressure Regulating Valve (PRV) family not only eliminates elastomers, exterior metal parts, and re-torqueing, it also provides easy maintenance and flexibility. The valves can be used in a wide range of markets including water treatment, chemical processing, microelectronics, pharmaceutical, life sciences, and solar. Notable of the new design is a patent pending 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 being elastomer free, high-purity operation is ensured via the valve's threaded bonnet that has no exposed metal bolts. Other features include a modular system that allows users to easily adjust the set pressure range and quickly go from reducing to retaining (or vice versa) by switching the cartridge. 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.
