BelGAS 627 Series - R627 High Flow Relieving Gas Pressure Regulator

The BelGAS R627 relieving gas pressure regulator features an internal valve that provides reliable protection against over pressurization, and in some cases, eliminates the need for an external relief valve. As output pressure builds above the start-to-discharge point, the relief seat disengages from the diaphragm and excess pressure is relieved through the bonnet vent port. As a result, output pressure reduces and returns to initial set point.
