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. When the coil is energized the pilot valve opens, relieving the pressure above the piston, which is then lifted from its seat by the plunger. Upon de-energizing the coil, a spring closes the pilot valve and opens a bleed passageway to permit pressure to build above the piston and seat it.
Application
To control the flow of Water, Oil, Air, Gas, Solvents, Brine, Vacuum and any other fluids not reactive with construction materials and free of sediment. This solenoid 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.
