Bulletin 71.1:S200 Introduction The quick-reacting S200 Series pressure reducing service regulator is typically used in an industrial or commercial installation to minimize the shock effect of sudden downstream load changes that might otherwise activate safety shutoff equipment. In such an installation, where gas consumption varies from almost nothing to several thousand standard cubic feet per hour (scfh) (or normal cubic meters per hour (Nm3/h)), snap-acting solenoid valves can cause sudden load changes.

Bulletin 71.1:S200 Internal Relief Several S200 Series regulators have relief across the diaphragm (Figure 5) to help minimize overpressure. Any outlet pressure above the start-to-discharge point of the nonadjustable relief spring moves the diaphragm off the relief seat, allowing excess pressure to bleed out through the screened stabilizer vent.
