2SK Series Stainless Steel 2/2-Way Solenoid Valve
- Direct Acting, Normally Open
- Port Size: 1/8"–2"
- Fluid Temperature: -5°C to 80°C (120℃ optional)
- Operating Pressure: 0–1.0MPa
- Media: air, water, oil, gas, steam
2SK series is a stainless steel solenoid valve designed to maintain continuous flow during power-off conditions. It is made from corrosion-resistant stainless steel (304/316), the valve offers a durable and compact structure, and provides fast response. The normally open (NO) configuration effectively reduces energy consumption while extending service life. Optional intelligent energy-saving coils and high-protection housings (IP67/IP68) offer dependable and cost-effective fluid control solutions in harsh or outdoor environments.
- Normally open design keeps the valve open during power-off conditions, ensuring uninterrupted media flow and system safety
- Durable stainless steel body (304 or 316 optional) with strong corrosion resistance
- Reliable zero-pressure start and direct-acting operation with fast response and large flow capacity
- Optional IP67/IP68 coil protection, which is suitable for humid, dusty, or outdoor environments
- Intelligent coil power adjustment reduces energy use by up to 30%, lowers heat generation, and extends service life
- Features a compact structure that enables flexible installation and easy integration into existing system/equipment or limited space
This solenoid valve is widely used in fluid control scenarios where powered-off protection and energy-saving performance are required, such as:
- Industrial automation control systems
- Water treatment systems
- Agricultural irrigations
- Chemical processing equipment
