With easier and safer operation in mind, the new PRVs feature a central housing nut that eliminates re-torqueing and injection molded arrows to indicate flow direction. Operational performance includes tightness resistant to temperature cycling with constant and low vibrating control behavior.
Other outstanding features include a modular system design that simplifies maintanance and reworks. With replaceable cartridges, users can simply swap out cartridges when needed while keeping a handy spare parts inventory. PRVs can be ordered with or without pressure gauges that can be installed on both sides of the valve in any position.
“Aggressive media and harsh application conditions are a reality in many of the processes found in the chemical industry,” says Jeff Sixsmith, Product Manager for Valves and Actuation for GF Piping Systems. “Our chemical resistant plastic PRVs meet the strictest safety and durability requirements for these demanding applications.”
Available in sizes from 3/8″ to 2″ (DN 10 – DN 50), standards include ISO 9393 for tightness and EN 12266 for leak rating. In addition to PVC and CPVC materials, PRVs are offered in PROGEF Standard PP, SYGEF Standard PVDF, and SYGEF Plus PVDF-HP.
