美國(guó)ASCO快速排氣閥/EFHC8321G001
先導(dǎo)式快速排 - 1/4“ - 3/8”
電磁先導(dǎo)式常閉和常開的建設(shè)提供活塞閥。可用交流或直流操作用黃銅或不銹鋼閥體。
這些閥門有三個(gè)管道連接和兩個(gè)小孔。當(dāng)一個(gè)孔是打開的，另一種是關(guān)閉，反之亦然。它們通常用于交替地施加壓力，以從一個(gè)閥門致動(dòng)器的排氣壓力或單作用氣缸。這些閥門可以常閉，常開或通用。
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。
蒸汽 - 專為高流量，高壓力的服務(wù)。非常適于電廠和類似的應(yīng)用。
飲用水和食品服務(wù) - NSF專為飲用水系統(tǒng)和食品服務(wù)設(shè)備的使用上市閥。
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)安全和非易燃現(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。
運(yùn)球控制 - 三通閥用于駕駛NAMUR致動(dòng)器。運(yùn)球控制閥脈沖空氣中的致動(dòng)器的進(jìn)出慢慢定位過(guò)程閥并在需要時(shí)將其固定到位。
磁保持 - 非常適于遠(yuǎn)程應(yīng)用中持續(xù)供電的設(shè)備不能使用，如天然氣井設(shè)備。
醫(yī)療/分析 - ASCO微型一般服務(wù)，隔離，捏，和比例閥用于液體和氣體的醫(yī)療設(shè)備和分析儀器的**和可靠的控制。

Pilot Operated Quick Exhaust – 1/4″ – 3/8″
Solenoid pilot operated piston valves available in normally closed and normally open constructions. Available either AC or DC operated with brass or stainless steel bodies.
These valves have three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa. They are commonly used to alternately apply pressure to an exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal.
General Service – Air/Inert Gas, Water, Lt. Oil (up to 300 SSU) service at moderate temperatures.
Steam – Designed for high flow, high pressure service. Ideal for power plants and similar applications.
Potable Water and Food Service – NSF listed valves designed for use in drinking water systems and food service equipment.
Air Operated – Uses auxiliary compressed air or water source to shift valve, rather than a solenoid operator.
Intrinsically Safe and Non-Incendive 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.
Dribble Control – 3–way valve are used for piloting NAMUR actuators. The dribble control valve pulses air in and out of the actuator to slowly position the process valve and hold it in place when desired.
Magnetic Latching – Ideal for remote applications where continuously powered devices can't be used, such as gas well equipment.
Medical/Analytical - ASCO Miniature general service, isolation, pinch, and proportional valves are utilized for the precise and reliable control of liquids and gases in medical equipment and analytical instrumentation.
