ASCO高流阀，美国ASCO五通电磁阀，8551G421
5 / 2 /高流量的空气，惰性气体，1 / 4″
在一个电磁阀的阀芯piloted建设。单或双电磁阀，交流或直流与铝或316不锈钢阀体。压力额定值（35 - 150 psi。
4路电磁阀
这些阀门有四个或五个管道连接，通常称为端口。一个压力入口，两缸端口提供双作用气缸或致动器和一个或两个出口压力的废气从气缸压力。他们有三种类型的建筑，一个电磁阀，电磁阀或双单空运操作。
一般服务–空气/惰性气体，水，油（300四）在中等温度下服务。
气动–使用辅助压缩空气或水源转换阀，而不是一个螺线管操作。
本质安全与非incendiver现场布线–仅用于本质安全和非易燃的现场布线领域。设计适当大小和批准的区域与电流和电压限制的障碍。
低功率0.55 W和1.4 W–低功率线圈提供PLC和DCS总线网络与传统布线的兼容性，减少电池消耗，减少布线成本，降低温升，节约能源。
寿命长/干空气–专为安静的操作，寿命长，可达20000000次，在干燥的空气或气体中的应用。

5/2 – High flow for air/inert gas – 1/4″
Internally piloted solenoid valve with spool construction. Single or double solenoid, AC or DC with aluminum or 316 stainless steel body. Pressure ratings of 35-150 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.
