EHCOTECH  N21E-3/4-OC-12VDC-ES  SOLENOID VALVE

3/4" NPT  |  12-Volt DC EHCO-Smart Coil | BASF Ultramid® PA 66 Body / EPDM Diaphragm |  Normally Open  |  3 - 90 psi


EHCOTECH N21-Series solenoid valves are an affortable but amazingly robust and dependable choice for a variety of water, air, and other general purpose liquid applications. Media being controlled must be compatible with Nylon 66, EPDM rubber, and Stainless Steel (300 and 400 series). The N21-series valves are semi-direct acting, making them suitable for many low differential pressure applications where traditional, pilot operated, solenoid valves may not perform reliably.

The N21-Series uses an EHCO-Smart coil with an internal “hit-and-hold” circuitry. The EHCO-Smart coil drastically drops the “hold” voltage and amperage to maintain a lower coil temperature for long coil life.
