Stainless Steel Solenoid Valve

Type "JR" Reduced Port

Normally Open - 3/8" to 1/2" Pipe Size

Fluid Temp: -350°F to 400°F | Max. Static Pressure - 300 PSI

No Differential Pressure Required to Open

Operation

Valve closes when energized and opens when de-energized. In this direct acting valve, when the coil is energized, the stem is pressed into its conical seat by the plunger.

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 (-30°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
