Type R627 Gas Pressure Relief Regulator
The BelGAS Type R627 gas pressure relief regulator features an internal valve that offers reliable protection against overpressurization—often eliminating the need for an external relief valve.
When output pressure exceeds the set point, the relief seat disengages from the diaphragm, and excess pressure is vented through the bonnet port. The output pressure then automatically resets to the original set point.
