2S series solenoid valve is engineered for corrosive media and demanding industrial fluid-control environments. Constructed from high-performance AISI 304/316 stainless steel and finished with precision electropolishing, with optional sealing materials of FKM or PTFE available, the valve provides excellent resistance to acids, alkalis, ozone exposure, chlorines, and other harsh environments. The valve delivers millisecond-level response, low maintenance, and reliable performance with protection ratings up to IP65/IP67/IP68, combining reliability, energy efficiency, and low maintenance needs.
- Full stainless steel body with electropolished finish, ensuring corrosion resistance against strong acids, alkalis, ozone-rich media and other highly corrosive media
- Optional FKM or PTFE sealing materials, extending service life by up to 300% in oxidative environments
- Copper-wound aluminum coil combining energy efficiency and over 1 million cycles of service life
- Supported protection rating IP65/IP67 and explosion-proof requirements
- Available in multiple port sizes (1/8"–2") and NPT/BSPP thread options, operating at 0–10 bar and heat resistant to 180°
- Passed rigorous salt spray testing, ozone chamber testing, and reliability testing, achieving stable performance with up to 40% lower maintenance costs
- Offers customization according to your needs
This solenoid valve is mainly used in specialized environments with corrosive media or high purity requirements, such as:
- Ozone generators
(concentration 0–200 g/m³) - Chemical dosing systems (pH 1–14)
- Semiconductor manufacturing
- Pharmaceutical processing
- Industrial water treatment
- Air compressors
- Car wash
- Laundry equipment
