The N4C-EB1 is a 24V AC ½” FNPT electric plastic solenoid valve requiring only 6 watts of power to actuate. The response time for this valve is extremely low, being less than one second. Since the valve is normally closed, it is closed while de-energized. In order to open the valve, the valve must be both energized and have a differential pressure of at least 5 psi to full open. This necessary differential pressure is due to the valve’s pilot operation, which also makes the valve unsuitable for gravity feed situations.
The coil enclosure is rated NEMA 4, which makes this valve a great choice for both indoor and outdoor projects. Windblown dust, ice forming damage, rainfall and hose-directed water are all protected against with this NEMA 4 enclosure. Be sure, however, that the valve is never fully submerged. The valve body consists of NORYL GTX830 resin which provides the valve with excellent heat and chemical resistance while also allowing for adequate stiffness.
This is a two-way valve, meaning it has two ports. It is also unidirectional, having an “In” port and an “Out” port. Media should only flow through the “In” port and out the “Out” port without any backpressure. The valve is not designed to withstand backpressure exerting into the “Out” port. Two 18” extending allow connection to a power supply.
