DF(ZCS)-25 二位二通水用电磁阀
DF(ZCS)-25 是一款专为水介质控制系统设计的常闭型二位二通电磁阀，适用于液体管路的自动化通断控制。该产品采用直动式结构，具备响应迅速、密封可靠、使用寿命长等特点，可广泛应用于家庭供水、商业循环系统、工业设备、农业灌溉及暖通空调等领域，满足多样化场景的流体控制需求。
结构与材质
阀体选用高强度黄铜铸造，表面经耐腐蚀镀层处理，适应不同水质环境。内部结构采用精密加工工艺，确保动作部件灵活性与密封性。线圈部分由全封闭式铜线绕组与环氧树脂封装技术制成，具备良好的绝缘与散热性能，可适应频繁启停工况。密封件选用耐磨橡胶或聚四氟乙烯材质，有效防止渗漏，兼容常温至中高温液体介质。
工作原理
电磁阀在断电状态下处于常闭状态，阀口由弹簧压力与介质压力共同作用保持密封。当线圈通电时，电磁力驱动阀芯克服弹簧阻力快速上移，阀门开启，介质流通；断电后，弹簧复位关闭阀门，切断水流。直动式设计省去了先导孔结构，使其在低压或静压工况下仍能稳定工作。
核心优势
- 高效节能：低功耗线圈设计，支持宽电压范围（AC/DC 12-240V可选），降低运行成本。
- 快速响应：开闭动作时间小于50毫秒，精准匹配自动化控制系统需求。
- 紧凑耐用：小型化结构设计节省安装空间，黄铜阀体与抗老化材料延长使用寿命。
- 安全稳定：全封闭线圈防护等级达IP65，可在潮湿或多尘环境中稳定运行。
技术参数
- 公称通径：DN25（1英寸）
- 压力范围：0.02~1.0 MPa
- 介质温度：-10℃~+90℃（橡胶密封）/ -10℃~+150℃（PTFE密封）
- 介质类型：清水、中性液体（需避免含颗粒、油污或强腐蚀性液体）
应用建议
安装时需注意介质流向与阀体箭头标识一致，建议前置过滤器以延长密封件寿命。定期检查线圈连接状态与阀体清洁度，确保长期稳定运行。本产品不适用于蒸汽、燃气或高压差频繁冲击场景。
English Introduction
DF(ZCS)-25 2-Position 2-Way Water Solenoid Valve
The DF(ZCS)-25 is a normally closed 2-position 2-way solenoid valve designed for water medium control systems. It features a direct-acting mechanism, providing rapid response, reliable sealing, and extended service life. Suitable for automated on/off control in liquid pipelines, this valve is widely used in residential water supply, commercial circulation systems, industrial equipment, agricultural irrigation, and HVAC applications.
Structure & Materials
The valve body is constructed from high-strength brass with anti-corrosion coating, ensuring durability in diverse water quality conditions. Precision-machined internal components guarantee smooth operation and leak-proof performance. The fully enclosed copper coil, encapsulated with epoxy resin, delivers excellent insulation and heat dissipation for frequent switching cycles. Seals made of wear-resistant rubber or PTFE materials ensure compatibility with liquids ranging from ambient to elevated temperatures.
Operating Principle
In its de-energized state, the valve remains closed by combined spring force and medium pressure. When energized, electromagnetic force lifts the plunger to open the valve instantly, allowing fluid flow. The direct-acting design eliminates the need for pilot channels, enabling reliable performance even under low-pressure or static pressure conditions.
Key Advantages
- Energy Efficiency: Low-power consumption coil supports wide voltage options (AC/DC 12-240V).
- Rapid Response: Actuation time under 50 ms ensures precise system synchronization.
- Compact Robustness: Space-saving brass construction with anti-aging materials enhances longevity.
- Operational Safety: IP65-rated coil protection ensures reliability in humid or dusty environments.
Technical Parameters
- Nominal Diameter: DN25 (1 inch)
- Pressure Range: 0.02~1.0 MPa
- Medium Temperature: -10℃~+90℃ (Rubber Seal) / -10℃~+150℃ (PTFE Seal)
- Compatible Media: Clean water, neutral liquids (avoid particles, oils, or highly corrosive fluids).
Usage Guidelines
Install with flow direction aligned to valve body markings. A pre-installed filter is recommended to prevent seal wear. Regular inspection of electrical connections and valve cleanliness is advised for optimal performance. Not recommended for steam, gas, or high-pressure differential applications.
