Elastomer-free design eliminates particle shedding for improved high purity operation

The product from GF Piping Systems also has no exterior metal parts and is designed for 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.
 
Key to the new design is a special piston that eliminates the use of elastomers in the valve, so ending particle shedding for improved high purity operation. 
 
Other 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 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 inches to 2 inches (DN 10 - DN 50). Standards include ISO 9393 for tightness and EN 12266 for leak rating.
