二位二通水用電磁閥，DF(ZCS)-20

產(chǎn)品概述

DF(ZCS)-20二位二通水用電磁閥是一款專為水、油、氣體等中性介質(zhì)設(shè)計的自動化控制閥門，適用于工業(yè)管路系統(tǒng)中的流體通斷控制。該產(chǎn)品采用先導(dǎo)式活塞結(jié)構(gòu)，具有響應(yīng)迅速、密封性能穩(wěn)定、使用壽命長等特點。其閥體材質(zhì)可根據(jù)需求選擇鑄鐵或黃銅，確保耐腐蝕性和承壓能力。工作壓力范圍為0.03~1MPa（直動式型號為0~0.6MPa），介質(zhì)溫度適應(yīng)0~75℃，環(huán)境溫度范圍為-10~+50℃，能滿足多種工況需求。電源支持AC 220V/380V/36V或DC 12V/24V/110V/220V等多種電壓規(guī)格，絕緣等級為B級，線圈溫升≤80℃，功耗低至12W（φ5~φ20規(guī)格）。安裝時需保持介質(zhì)流向與閥體箭頭一致，線圈垂直向上，傾斜度不超過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

核心特點

該電磁閥采用先導(dǎo)式設(shè)計，主閥與導(dǎo)閥協(xié)同工作，通過電磁力驅(qū)動鐵芯實現(xiàn)快速啟閉，動作時間≤1秒（關(guān)閉≤2秒）。閥體結(jié)構(gòu)緊湊，法蘭或內(nèi)螺紋連接方式靈活（如DF-20型號為G3/4″內(nèi)螺紋），適配不同管道需求。介質(zhì)粘度需≤20CST，適用于清潔或輕度污染的液體環(huán)境。線圈采用防水設(shè)計，溫升控制優(yōu)異，電源波動容忍度達-15%~+10%，適應(yīng)不穩(wěn)定電網(wǎng)環(huán)境。產(chǎn)品廣泛用于給排水、空調(diào)、消防、清洗設(shè)備及工業(yè)自動化領(lǐng)域，尤其適合需要頻繁開關(guān)或遠程控制的場景。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

應(yīng)用場景

該產(chǎn)品適用于自動化控制水、熱水、中性氣體及低粘度油類介質(zhì)的管路系統(tǒng)，如鍋爐給水、冷卻循環(huán)系統(tǒng)、灌溉設(shè)備、液體分配裝置等。在食品加工、紡織印染、制藥等行業(yè)的流體控制環(huán)節(jié)中表現(xiàn)優(yōu)異。其鑄鐵閥體版本適用于普通工業(yè)環(huán)境，而黃銅版本則更適合對材質(zhì)衛(wèi)生性要求較高的場合。安裝時建議在閥前加裝過濾器以延長使用壽命，并定期檢查密封性能。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
