English Introduction:
The 2WBK250-25 is a Normally Open (N.O.) 2-port 2-position solenoid valve designed for industrial fluid control systems. It is suitable for automated on/off control of neutral media such as liquids and gases. The normally open structure ensures the valve remains open during power failure and closes automatically when energized, making it ideal for applications requiring fail-safe protection or emergency shut-off.
Core Structure & Operation
Utilizing a direct-acting mechanism, the valve body is constructed from high-strength brass or stainless steel (optional), with sealing components made of wear-resistant engineering rubber or fluoropolymer for compatibility with temperatures ranging from -10℃ to +120℃. The compact internal structure enables rapid flow path switching through electromagnetic coil-driven core movement. A spring reset function restores the valve to its normally open state upon power loss.
Technical Specifications
- Pressure Range: 0~25 bar
- Media Temperature: -10℃~+120℃ (material-dependent)
- Port Size: G1/4 to G1 (customizable)
- Voltage Options: DC12V~DC24V, AC24V~AC220V
- Protection Class: IP65 for harsh environments
Applications
This valve is widely used in water treatment systems, chemical process control, HVAC equipment, and industrial machinery. It is particularly effective in scenarios requiring emergency shutdown or long-term stable operation, such as cooling water circulation, compressed air management, and hydraulic system protection.
Key Advantages
- Enhanced Durability: Optimized coil and core assembly ensures rapid response and extended service life.
- Energy Efficiency: Low-power consumption design supports continuous operation.
- Adaptability: Multiple voltage and port configurations for diverse industrial needs.
- Easy Maintenance: Modular structure allows quick disassembly and seal replacement.
