Emerson introduces the ASCO ™ Series 551-553 pilot operated solenoid valves that can now also be used at temperatures as low as -60°C, thus considerably expanding its application options for our customers in the process industry and food industry. Due to the increasing interest in oil and gas exploration in environments with extreme (arctic) conditions, this extension of the temperature range offers a reliable solution.
Moreoever, we now have the possibility to control both single and double acting actuators. This is the first 5/2 pilot operated solenoid valve for double acting actuators which can operated at this low temperature level.
Customers can take advantage of the same excellent performance, long life and safety certifications that the 551/553 Series always offers, and now even under extreme arctic conditions. These spool valves are available with the following certifications: ATEX, IECEX, UL, CSA and CUTR. SIL3 certification is available as of June 2019.
