世格直動式滑閥結(jié)構(gòu)原理，NFB215C020 51DC

Features

? “LT” suffix valves are built to control cryogenic fluids,

including liquid oxygen (-297°F/-181°C), liquid argon

(-303°F/-184°C), and liquid nitrogen (-320°F/-194°C)

? All suffix “LT” valves are degreased, cleaned, tested

free of moisture, and black light tested for hydrocarbons

? Liquid CO2 valves are suitable for remote mounting or

for direct mounting to the refrigerated component by

using four-hole bracket, provided

 Once opened at higher pressure, valve will remain open to 3 psi at inlet.

0 psi on AC construction, 1/4 psi on DC construction.

 EPDM disc.

* Ambient temperature range 32°F - 140°F; ** Ambient temperature range 32°F - 77°F

 Once opened at higher pressure, valve will remain open to 0.2 bar at inlet.

0 bar on AC construction, 0.02 bar on DC construction.
