New elastomer-free pressure regulating valve from GFPS is ‘market-first’

GF Piping Systems has announced availability of a new Pressure Regulating Valve (PRV) family with an elastomer-free design to stop particle shedding.

The new valves eliminate elastomers, exterior metal parts and re-torqueing, and can be used in a range of markets including water treatment, chemical processing, microelectronics, pharmaceutical, life sciences, and solar.

Key to the new design is a unique 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 its elastomer-free capability provided by the proprietary 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.
