Description
3/8 Inch Plastic Delrin Solenoid Valve 2/2 Normally Open – CS Fluid Power NOPA14
A corrosion-resistant, pressure-assisted 2/2 way normally open solenoid valve manufactured from POM (Delrin®) and designed for water, RO water, demineralised water and mildly aggressive fluid applications. The NOPA14 Series provides fail-safe open operation, remaining open without power and closing when energised, making it ideal for water treatment systems, dosing equipment and industrial process applications.
