Introduction The quickreacting S200 Series pressure reducing service regulators are typically used in industrial or commercial installations to minimize the shock effect of sudden downstream load changes that might otherwise activate safety shutoff equipment. In such an installation, gas consumption varies from almost nothing to several thous stard cubic feet or normal cubic meters per hour (SCH or m³/h(n)), snapacting solenoid valves can cause sudden load changes. In addition, the S200 Series has an integral monitor regulator that works independently of the main regulator to provide overpressure protection in case of main regulator failure.
