電磁閥，DF-25

DF-25電磁閥產(chǎn)品概述

DF-25電磁閥是一種采用先導(dǎo)式結(jié)構(gòu)的工業(yè)自動(dòng)化控制元件，專為液體、氣體及低粘度油介質(zhì)（20CST以下）的管路控制設(shè)計(jì)。該產(chǎn)品通過電磁線圈產(chǎn)生的磁力驅(qū)動(dòng)閥芯動(dòng)作，實(shí)現(xiàn)流體的二位式通斷控制，具有響應(yīng)快速（開啟≤2秒/關(guān)閉≤1秒）、密封性能優(yōu)良等特點(diǎn)。閥體采用黃銅或不銹鋼材質(zhì)，支持G1"內(nèi)螺紋連接，工作壓力范圍0.03-0.8MPa，可適應(yīng)-10℃至+80℃的環(huán)境溫度，線圈可選AC220V/380V或DC24V等多種電壓規(guī)格。其緊湊的結(jié)構(gòu)設(shè)計(jì)允許傾斜30°安裝，廣泛應(yīng)用于石油、化工、食品加工等行業(yè)的流體自動(dòng)化系統(tǒng)。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

技術(shù)特點(diǎn)與優(yōu)勢(shì)

該電磁閥采用膜片式密封結(jié)構(gòu)，主閥與導(dǎo)閥協(xié)同工作，在低壓或零壓差條件下仍能穩(wěn)定啟閉。特殊設(shè)計(jì)的增強(qiáng)型橡膠膜片可承受1.6MPa瞬時(shí)壓力沖擊，線圈經(jīng)真空浸漆處理并采用熱固性塑料包覆，確保在潮濕等惡劣環(huán)境中長(zhǎng)期穩(wěn)定運(yùn)行。介質(zhì)流向需與閥體箭頭標(biāo)識(shí)一致，建議配套安裝過濾器以延長(zhǎng)使用壽命。產(chǎn)品提供常閉型（DF）和常開型（DF-K）兩種工作模式，滿足不同工況需求。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

應(yīng)用領(lǐng)域

適用于水處理、暖通空調(diào)、制藥設(shè)備等場(chǎng)景的流體控制，特別在需要遠(yuǎn)程電子控制的系統(tǒng)中表現(xiàn)優(yōu)異。在食品飲料行業(yè)可用于灌裝線控制，環(huán)保領(lǐng)域適用于污水處理設(shè)備，輕工業(yè)中常見于造紙機(jī)械的潤(rùn)滑系統(tǒng)。該產(chǎn)品不能用于強(qiáng)腐蝕性介質(zhì)或含固體顆粒的流體，使用前需確認(rèn)介質(zhì)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 -介質(zhì) compatibility must be verified prior to use. 202526
