PFR600

The PFR600 is a double stage gas pressure regulator by Pietro Fiorentini.
Designed to ensure continuous gas supply while maintaining a high level of safety with reduced emission.

The PFR600 is a service regulator without slam-shut device, incorporating a double token relief valve (IRV) with partial relief capacity. It is particularly suitable for low pressure natural gas distribution systems for residential users. It should be used with previously filtered non-corrosive gases including biomethane and RNG (Renewable Natural Gas).

The PFR600 is Hydrogen Ready for NG-H2 blending.
