The Cronos Series regulators are accurate pilot-operated, pressure balanced, soft seated regulators designed for high pressure transmission/city gate, large capacity distribution systems and power plant feeds. They provide smooth, quiet operation, tight shutoff and long life. The regulator utilizes a main valve actuator, Type PRX pressure reducing pilot, and Type SA/2 pilot supply regulator or Type PS compact pressure reducing pilot.

The superior performance of this regulator is due to the amplifying effect of the pilot and the two-path control system. Changes in outlet pressure act quickly on the actuator diaphragm to provide fast response to system change. Then the pilot amplifies any small system changes to position the main valve for precise pressure control.
