ASCO先導(dǎo)空氣電磁閥/USF8345B002
4/2 - 結(jié)構(gòu)緊湊，空氣/惰性氣體，水，油中尉 - 1/4“
電磁先導(dǎo)閥可用交流或直流操作用黃銅或316不銹鋼的身體。 10-150 psi工作壓力。
4通電磁閥
這些閥門有四個(gè)或五個(gè)管道連接，通常稱為端口。一個(gè)壓力入口， 2缸口提供壓力的雙動(dòng)氣缸或致動(dòng)器和一個(gè)或兩個(gè)出口，從氣缸的排氣壓力。他們有三個(gè)類型的建筑，單穩(wěn)，雙電磁閥或單航空運(yùn)營(yíng)。
一般事務(wù) - 空氣/惰性氣體，水，油中將（高達(dá)300 SSU ）服務(wù)在中等溫度下。
氣動(dòng) - 使用輔助壓縮空氣或水源轉(zhuǎn)向閥，而不是一個(gè)螺線管操作者。
本質(zhì)安全和非Incendiver現(xiàn)場(chǎng)接線，對(duì)于只使用本質(zhì)安全和非易燃現(xiàn)場(chǎng)接線的地方。專為適當(dāng)大小和批準(zhǔn)的區(qū)域與電流和電壓限制的障礙。
低功耗 - 0.55 W和1.4 W低功率線圈提供PLC和DCS兼容性BUS網(wǎng)絡(luò)和傳統(tǒng)的布線，減少電池消耗，降低了布線成本，降低溫升，節(jié)約能源。
長(zhǎng)壽命/干燥空氣 - 專為安靜的操作，壽命長(zhǎng)，可達(dá)20萬(wàn)次，在干燥的空氣或氣體應(yīng)用。

4/2 - Compact, Air/inert Gas, Water,Lt Oil – 1/4″
Solenoid pilot operated valves available AC or DC operated with brass or 316 stainless steel bodies. Operating pressures of 10-150 psi.
4-Way Solenoid Valves
These valves have four or five pipe connections, commonly called ports. One pressure inlet, two cylinder ports providing pressure to the double acting cylinder or actuator and one or two outlets to exhaust pressure from the cylinders. They have three types of construction, single solenoid, dual solenoid or single air operator.
General Service – Air/Inert Gas, Water, Lt. Oil (up to 300 SSU) service at moderate temperatures.
Air Operated – Uses auxiliary compressed air or water source to shift valve, rather than a solenoid operator.
Intrinsically Safe and Non-Incendiver Field Wiring –For use only in intrinsically safe and Non-Incendive Field Wiring areas. Designed for properly sized and approved areas with current and voltage limiting barriers.
Low Power – 0.55 W and 1.4 W low wattage coil to provide PLC and DCS compatibility for BUS network and traditional wiring, reduced battery drain, reduced wiring cost, reduced temperature rise, energy savings.
Long Life / Dry Air – Designed for quiet operation and long life, up to 20 million cycles, in dry air or gas applications.
在的不同位置開有通孔，每個(gè)孔都通向不同的油管，腔中間是閥，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會(huì)被吸引到哪邊，通過控制閥體的移動(dòng)來檔住或漏出不同的排油的孔，而進(jìn)油孔是常開的，液壓油就會(huì)進(jìn)入不同的排油管，然后通過油的壓力來推動(dòng)油剛的活塞，活塞又帶動(dòng)活塞桿，活塞竿帶動(dòng)機(jī)械裝置動(dòng)。這樣通過控制電磁鐵的電流就控制了機(jī)械運(yùn)動(dòng)。
追溯的發(fā)展史，到目前為止，國(guó)內(nèi)外的從原理上分為三大類(即：直動(dòng)式、分步直動(dòng)、先導(dǎo)式)，而從閥瓣結(jié)構(gòu)和材料上的不同與原理上的區(qū)別又分為六個(gè)分支小類(直動(dòng)膜片結(jié)構(gòu)、分步重片結(jié)構(gòu)、先導(dǎo)膜式結(jié)構(gòu)、直動(dòng)活塞結(jié)構(gòu)、分步直動(dòng)活塞結(jié)構(gòu)、先導(dǎo)活塞結(jié)構(gòu))。
