The ZS stainless steel normally open series solenoid valve has the same parameters as the ZS brass normally open series, but adopts stainless steel material for better corrosion resistance. Normally open (close on energization) design, port sizes 1/8 to 1/2 inch, working pressure 0-1.0MPa, suitable for water, air, oil, gas, and corrosive media environments.

Product Features
Stainless steel material, corrosion resistance superior to brass version
Normally open design: valve opens when de-energized, suitable for applications requiring normally-pass safety conditions
Suitable for weak acid, weak alkali and other corrosive media
Multiple port sizes available: 1/8 to 1/2 inch
Multiple voltage options: AC220V, DC24V, DC12V
Explosion-proof coil optional for gas applications
Selection and Installation Guide
Normally open (close on energization) rather than normally closed - always confirm action mode during selection
For corrosive media, select 316 stainless steel material
Select port size based on flow CV value and pipeline dimensions
If medium contains impurities, a filter of at least 80 mesh must be installed
Install with valve body arrow aligned with fluid flow direction, coil vertically upward
For gas applications, explosion-proof coil must be selected and comply with local explosion-proof standards
Keep voltage fluctuation within +/-10% to avoid coil burnout
