Description
These solenoid valves withstand the severe service
encountered in controlling cryogenic fluids such as liquid oxygen (-297°F),
liuquid argon (-303&def;F) and liquid nitrogen (-320°F).
All suffix "LT" valves are degreased, cleaned and tested to
keep them free of moisture. In addition, these valves are "black
light" tested for hydrocarbons.
Series 8264 Liquid CO2 valves are suitable for remote
mounting of for direct mounting to the refrigerated component by using
the four-hole bracket provided.
Important Install tubing with an inside diameter no larger
than the valve orifice in the outlet port to locate the refrigeration
point ddownstream of the the valve and to prevent freezing of the
expanding CO2 inside the valve body.
