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). Cryogenic valves are degreased and cleaned to keep them free of moisture. Oxygen valves are "black light" tested. Valve operates from zero to maximum differential pressure indicated in table.
(12) Operation: Valve opens when energized and closes when de-energized. In this direct acting valve, when the coil is energized, the stem is lifted from its conical seat by the plunger.
(12) 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.
