ZS Stainless Steel Normally Open Series Solenoid Valve
Model：ZS-25
Category：ZS Series
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 & 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
