Bronze Solenoid Valve
Type "NR" Reduced Port
Normally Closed - 1/2" to 3/4" Pipe Size
Max. Fluid Temp. - 212°F | Max. Static Pressure - 300 PSI
No Differential Pressure Required to Open
Direct Acting - Orifice Sizes 1/8" to 1/2"
Operation
This solenoid 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.
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). The solenoid valve operates from zero to maximum differential pressure indicated in table. This solenoid valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
