ECL502 Series Cryogenic Economizer

Product Description

Application

ECL502 series cryogenic economizers are designed to be used as pressure reducing valves to automatically maintain a constant inlet or back pressure, normally closed at pressures below its set point and open at pressures above its set point. The ECL502 is primarily designed to assist in maintaining a desired system pressure ideal for Nitrogen, Oxygen, Argon and other cryogenic cylinder applications with a 100% performance improvement over RegOs ECLXXX series. ECL502 series offers outstanding performance for maintaining LNG fuel line pressure.

Features

ECL502 series design provides premium flow characteristics allowing for fast pressure reduction while maintaining sensitive flow control at lower pressure settings.

All materials of construction- copper alloy, PTFE and stainless steel were selected for compatibility with cryogenic service.

150 count mesh Monel screens installed into the inlet and outlet ports prevent debris from entering or damaging any downstream components.

Interchangeable with existing cryogenic economizer units.
