S200 Series Pressure Reducing Regulators

S200 Series Pressure Reducing Regulators 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. The resulting shock pressures and regulator instability can cause safety equipment to shut the installation down. But with an S200 Series regulator, transmission of shock loads to downstream equipment is reduced, thereby helping maintain downstream pressures within desired limits.
