美国ASCO快速排气阀/EFHC8321G001
先导式快速排 - 1/4“ - 3/8”
电磁先导式常闭和常开的建设提供活塞阀。可用交流或直流操作用黄铜或不锈钢阀体。
这些阀门有三个管道连接和两个小孔。当一个孔是打开的，另一种是关闭，反之亦然。它们通常用于交替地施加压力，以从一个阀门致动器的排气压力或单作用气缸。这些阀门可以常闭，常开或通用。
一般事务 - 空气/惰性气体，水，油中将（高达300 SSU ）服务在中等温度下。
蒸汽 - 专为高流量，高压力的服务。非常适于电厂和类似的应用。
饮用水和食品服务 - NSF专为饮用水系统和食品服务设备的使用上市阀。
气动 - 使用辅助压缩空气或水源转向阀，而不是一个螺线管操作者。
本质安全和非易燃现场接线，对于只使用本质安全和非易燃现场接线的地方。专为适当大小和批准的区域与电流和电压限制的障碍。
低功耗 - 0.55 W和1.4 W低功率线圈提供PLC和DCS兼容性BUS网络和传统的布线，减少电池消耗，降低了布线成本，降低温升，节约能源。
长寿命/干燥空气 - 专为安静的操作，寿命长，可达20万次，在干燥的空气或气体应用。
运球控制 - 三通阀用于驾驶NAMUR致动器。运球控制阀脉冲空气中的致动器的进出慢慢定位过程阀并在需要时将其固定到位。
磁保持 - 非常适于远程应用中持续供电的设备不能使用，如天然气井设备。
医疗/分析 - ASCO微型一般服务，隔离，捏，和比例阀用于液体和气体的医疗设备和分析仪器的**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.
