New GF Elastomer-Free High Purity Valve Design Stops Particle Shedding

Pressure Regulating Valves offer new piston design that does away with elastomers for blog6img01improved high purity operation

GF Piping Systems has announced availability of a revolutionary new Pressure Regulating Valve (PRV) family that not only eliminates elastomers, exterior metal parts and re-torqueing; it also provides easy maintenance and flexibility.  These one-of-a-kind 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 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.

“Our new Pressure Regulating Valve family offers solutions that no one else in the PRV market offers,”  says Jeff Sixsmith, Product Manager for Valves and Actuation for GF Piping Systems.  “The piston design that makes it elastomer-free, is truly unique.  And, the modular system makes changing the valve function from pressure reducing to pressure retaining extremely easy.”

blog6img02Unique piston design makes this valve elastomer-free. 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, and 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.
