制冷电磁阀，FDF-19
产品概述
FDF-19制冷电磁阀是一种专为制冷系统设计的常闭型电动阀门，适用于控制氟利昂制冷剂（如F12、F22、F502）、水、气体及高温蒸气等介质的通断。该产品通过电信号实现远程自动化控制，广泛应用于冷冻机械、空调装置、化工设备、食品加工及纺织机械等领域，能有效调节管路中介质的流动方向或切断流量。其设计兼顾性能稳定性与操作便捷性，适合在-40℃至+105℃的介质温度范围内工作。128
结构特点
FDF-19采用黄铜阀体与进口耐腐蚀膜片材料，确保长期使用的密封性和耐用性。电磁线圈采用全封塑工艺，具备优异的绝缘、防水及抗振性能。阀门结构紧凑，安装方式灵活，支持铜管喇叭口连接（接管尺寸φ22×1.5mm），垂直安装时线圈朝上以优化性能。主阀采用导阀式（伺服式）结构，通电时通过磁场驱动导阀芯形成压差，推动主阀快速开启；断电时通过弹簧复位关闭，响应迅速且能耗低。1614

应用场景
FDF-19适用于制冷系统的液管路、吸气管路及热气旁通管路，可集成于冷库、中央空调、热泵机组等设备中。其稳定性和快速启闭特性使其在需要精确控温或频繁切换的工业场景中表现优异，如食品冷冻生产线、医药冷链仓储等。安装时需保持管道清洁，建议前置过滤器以避免杂质堵塞。51019
Product Overview
The FDF-19 refrigeration solenoid valve is a normally closed electric valve designed for refrigeration systems, suitable for controlling the flow or shut-off of refrigerants (e.g., F12, F22, F502), water, gases, and high-temperature steam. It enables remote automation via electrical signals and is widely used in freezing equipment, HVAC systems, chemical plants, and food processing. Its operational temperature range covers -40℃ to +105℃, ensuring reliability in diverse environments.1814
Design Features
The valve body is constructed from brass with corrosion-resistant diaphragms, while the fully encapsulated coil provides insulation, water resistance, and vibration resistance. Its compact design supports vertical installation (coil upward) with φ22×1.5mm flare tube connections. The servo-assisted mechanism ensures fast response: energizing the coil opens the pilot valve to create pressure differentials for main valve activation, while de-energizing resets the valve via spring force. This design balances efficiency with low energy consumption.61725
Technical Specifications
- Pressure Range: 0.03~2.1MPa (gas), 0.03~1.7MPa (liquid).
- Voltage Options: AC 24V-380V or DC 12V-220V.
- Media Compatibility: Compatible with refrigerants, air, water, and oils (<4°E viscosity).
- Environmental Limits: Operates at ≤50℃ ambient temperature and ≤85% humidity.
- Flow Capacity: Kv value of 4.5m³/h (water).2819
Applications
Ideal for liquid lines, suction lines, and hot gas bypass in refrigeration systems, the FDF-19 is commonly integrated into cold storage units, central air conditioning, and heat pumps. Its precision control suits industrial applications requiring temperature stability, such as frozen food production or pharmaceutical storage. Installation requires clean pipelines and a recommended upstream filter.51025
