电磁阀，DF-25

DF-25电磁阀产品概述

DF-25电磁阀是一种采用先导式结构的工业自动化控制元件，专为液体、气体及低粘度油介质（20CST以下）的管路控制设计。该产品通过电磁线圈产生的磁力驱动阀芯动作，实现流体的二位式通断控制，具有响应快速（开启≤2秒/关闭≤1秒）、密封性能优良等特点。阀体采用黄铜或不锈钢材质，支持G1"内螺纹连接，工作压力范围0.03-0.8MPa，可适应-10℃至+80℃的环境温度，线圈可选AC220V/380V或DC24V等多种电压规格。其紧凑的结构设计允许倾斜30°安装，广泛应用于石油、化工、食品加工等行业的流体自动化系统。1615

DF-25 Solenoid Valve Product Overview

The DF-25 is a pilot-operated solenoid valve designed for automated control of liquid, gas, and low-viscosity oil (below 20CST) in industrial pipelines. Its electromagnetic coil drives the valve core to achieve quick on/off switching (opening ≤2s/closing ≤1s), featuring reliable sealing and brass/stainless steel body construction. With 1" female thread connection, it operates under 0.03-0.8MPa pressure range and -10℃ to +80℃ ambient temperature. The tilt-tolerant design (up to 30°) accommodates flexible installation, while optional coil voltages include AC220V/380V and DC24V. Typical applications cover petroleum, chemical processing, and food production systems requiring precise fluid control. 7919

技术特点与优势

该电磁阀采用膜片式密封结构，主阀与导阀协同工作，在低压或零压差条件下仍能稳定启闭。特殊设计的增强型橡胶膜片可承受1.6MPa瞬时压力冲击，线圈经真空浸漆处理并采用热固性塑料包覆，确保在潮湿等恶劣环境中长期稳定运行。介质流向需与阀体箭头标识一致，建议配套安装过滤器以延长使用寿命。产品提供常闭型（DF）和常开型（DF-K）两种工作模式，满足不同工况需求。51113

Technical Features

The valve employs a diaphragm sealing system with coordinated main/pilot valve operation, enabling stable performance even under low-pressure conditions. Reinforced rubber diaphragm withstands 1.6MPa instantaneous pressure surges, while vacuum-impregnated coils with thermosetting plastic coating ensure durability in harsh environments. Flow direction must align with body markings, and inline filters are recommended for extended service life. Both normally closed (DF) and normally open (DF-K) variants are available to accommodate diverse operational requirements. 121621

应用领域

适用于水处理、暖通空调、制药设备等场景的流体控制，特别在需要远程电子控制的系统中表现优异。在食品饮料行业可用于灌装线控制，环保领域适用于污水处理设备，轻工业中常见于造纸机械的润滑系统。该产品不能用于强腐蚀性介质或含固体颗粒的流体，使用前需确认介质兼容性。4824

Applications

Ideal for fluid control in water treatment, HVAC, and pharmaceutical equipment, particularly in systems requiring remote electronic actuation. It serves effectively in food/beverage filling lines, wastewater treatment plants, and paper machine lubrication systems. Not suitable for strongly corrosive media or fluids containing solid particles -介质 compatibility must be verified prior to use. 202526
