BRONZE SOLENOID VALVE
TYPE "MR"

NORMALLY OPEN - 3/8" TO 3/4" PIPE SIZE
NO DIFFERENTIAL PRESSURE REQUIRED TO OPEN

Specifications:
Max. Fluid Temperature = 400°F
Max. Static Pressure = 150PSI

APPLICATION:
To control the flow of Steam, Hot Liquids, Hot Gases, Cryogenics** and any other fluids not reactive with construction materials and free of sediment. Cryogenic fluids include Liquid Oxygen (-297°F), Liquid Argon (-303°F) and Liquid Nitrogen (-320°F). Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.

Cleaning:
Cryogenic valves are degreased and cleaned to keep them free of moisture
Oxygen valves are also “black light” tested.
