The Cronos Series regulators, manufactured by Emerson®, is designed for immense tension transportation, extensive quantity circulation systems and power plant feeds with an exact pilot-operated, and flexible seated of something that regulates. It makes use of a main valve actuator, Type PRX pressure compressing pilot, and Type SA/2 pilot quantity regulator or Type PS condense tension reduction pilot that provides a smooth, quiet operation, tight shutoff and long life. Due to the increasing result of the pilot and the two-path control system, it provides high performance and has a quick reaction to system replacement that is due to the substitution in the outlet pressure that operates rapidly on the diaphragm of the actuator.
