二位二通水用电磁阀，DF(ZCS)-20

产品概述

DF(ZCS)-20二位二通水用电磁阀是一款专为水、油、气体等中性介质设计的自动化控制阀门，适用于工业管路系统中的流体通断控制。该产品采用先导式活塞结构，具有响应迅速、密封性能稳定、使用寿命长等特点。其阀体材质可根据需求选择铸铁或黄铜，确保耐腐蚀性和承压能力。工作压力范围为0.03~1MPa（直动式型号为0~0.6MPa），介质温度适应0~75℃，环境温度范围为-10~+50℃，能满足多种工况需求。电源支持AC 220V/380V/36V或DC 12V/24V/110V/220V等多种电压规格，绝缘等级为B级，线圈温升≤80℃，功耗低至12W（φ5~φ20规格）。安装时需保持介质流向与阀体箭头一致，线圈垂直向上，倾斜度不超过30°。1626

Product Overview

The DF(ZCS)-20 2/2-way water solenoid valve is designed for automated control of neutral fluids such as water, oil, and gas in industrial pipeline systems. Featuring a pilot-operated piston structure, it ensures rapid response, reliable sealing, and extended service life. The valve body is available in cast iron or brass for enhanced corrosion resistance and pressure tolerance. Operating parameters include a pressure range of 0.03~1MPa (0~0.6MPa for direct-acting models), medium temperature tolerance of 0~75°C, and ambient temperature suitability from -10~+50°C. It supports multiple power options including AC 220V/380V/36V and DC 12V/24V/110V/220V, with B-grade insulation and low power consumption (12W for φ5~φ20 models). Installation requires aligning the medium flow direction with the valve arrow and maintaining the coil vertically upright (max. 30° tilt).62027

核心特点

该电磁阀采用先导式设计，主阀与导阀协同工作，通过电磁力驱动铁芯实现快速启闭，动作时间≤1秒（关闭≤2秒）。阀体结构紧凑，法兰或内螺纹连接方式灵活（如DF-20型号为G3/4″内螺纹），适配不同管道需求。介质粘度需≤20CST，适用于清洁或轻度污染的液体环境。线圈采用防水设计，温升控制优异，电源波动容忍度达-15%~+10%，适应不稳定电网环境。产品广泛用于给排水、空调、消防、清洗设备及工业自动化领域，尤其适合需要频繁开关或远程控制的场景。179

Key Features

With a pilot-operated mechanism, the valve achieves fast switching (open ≤1s, close ≤2s) via electromagnetic actuation. Its compact design offers flexible connections—flanged or threaded (e.g., G3/4″ internal thread for DF-20)—to accommodate diverse piping systems. Compatible with fluids ≤20CST viscosity, it performs well in clean or mildly contaminated liquid environments. The waterproof coil exhibits minimal temperature rise (±80°C) and withstands voltage fluctuations (-15%~+10%), ensuring stability under erratic power supply. Ideal for applications like water supply/drainage, HVAC, firefighting, and automated industrial systems requiring frequent cycling or remote operation.7927

应用场景

该产品适用于自动化控制水、热水、中性气体及低粘度油类介质的管路系统，如锅炉给水、冷却循环系统、灌溉设备、液体分配装置等。在食品加工、纺织印染、制药等行业的流体控制环节中表现优异。其铸铁阀体版本适用于普通工业环境，而黄铜版本则更适合对材质卫生性要求较高的场合。安装时建议在阀前加装过滤器以延长使用寿命，并定期检查密封性能。52026

Applications

This valve suits pipeline systems handling water, hot water, neutral gases, and low-viscosity oils, including boiler feedwater, cooling circuits, irrigation systems, and liquid distribution units. It excels in fluid control for food processing, textile dyeing, and pharmaceutical industries. The cast iron variant fits general industrial environments, while the brass version meets higher hygiene standards. Recommended practices include installing upstream filters and periodic seal inspections for optimal performance.52026
