Stainless Steel Solenoid Valve

Type "KR" Full Port

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

Fluid Temp: -350°F to 400°F | Max. Static Pressure - 300 PSI
(Except valves listed for 500 PSI)

No Differential Pressure Required to Open

Operation

Valve closes when energized and opens when de-energized. When the coil is energized the plunger presses the poppet, closing the pilot orifice, and opens a bleed passageway to permit pressure to build above the piston and seat it. Upon de-energizing the coil, the pilot orifice is opened, relieving the pressure above the piston allowing it to leave its seat. The bottom spring allows the valve to operate at zero pressure drop.

Application

To control the flow of Corrosive Fluids, Deionized Water, Condensate, Ammonias, Vegetable Oils, Fuel Oils, Cryogenics**, Flammable Liquids. 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.
