ASCO通用阀控制中性气体的流量。它们以使用寿命长和响应速度快而著称，适用于多种安装配置。 
螺线管是阀门的电磁部分，由线圈，芯管，芯和外壳组成。ASCO RedHat品牌提供世界上最大的2通，3通和4通电磁阀选择，专为应对最苛刻的流体控制应用而设计。
ASCO的2通电磁阀具有一个入口和一个出口，用于允许和切断流体流动。两种类型的操作是常闭（NC）和常开（NO）。两通电磁阀有两种类型的结构，它们是直接作用的并且是内部先导的。
在直接作用结构中，电磁阀通电，铁芯直接打开常闭阀的孔或关闭常开阀的孔。阀门将在0 psi至其额定最大压力下运行。
内部先导结构使用管线压力来辅助操作。当线圈断电时（在常闭阀上），先导孔关闭，管路压力通过放气孔施加到活塞或隔膜的顶部，从而关闭阀。
ASCO三通电磁阀具有三个管道连接和两个节流孔。当一个孔口打开时，另一个孔口关闭，反之亦然。它们通常用于将压力交替施加到来自阀门执行器或单作用气缸的排气压力。这些阀可以常闭，常开或通用。
ASCO四通电磁阀具有四个或五个管道连接，通常称为端口。一个压力入口，两个气缸端口为双作用气缸或执行器提供压力，以及一个或两个出口以从气缸中排出压力。它们具有三种结构类型：单螺线管，双螺线管或单气动操作器。

RedHat Next Generation is the future of solenoid valve
technology, designed and manufactured to provide new
capabilities. The Next Generation of solenoid valves provides
lower operating cost, and represents an advancement
in the performance, reliability, and ruggedness that you
have come to expect from ASCO.
RedHat Next Generation valves use electronics technology
to manage power, providing a new standard of operation.
The solenoid incorporates a power management circuit
providing lower power consumption, enhanced pressure
and flow ratings, and electrical surge suppression to
both the solenoid and electronic controls.
The new solenoid draws only 1.2 watts of power for 12-24V
DC and 1.5 watts for 24-120V AC/DC, 100-240V AC/DC. A
conventional solenoid with the same performance can draw
as high as 17 watts of power. The savings in power usage
over the installed life of the valve will lower the total cost of
ownership up to 14%.
The new technology accepts both AC and DC voltages
without sacrificing flow or pressure specifications. DC performance
has been increased by 150% to 500% from today’s
industry standards, making the valves’ DC characteristics
equivalent to AC pressure and flow values. This simplifies your
control by eliminating the need for AC output cards, reduces
wiring costs, and provides safer working environments for
users operating on DC.
RedHat Next Generation coils are offered in three voltage
ranges covering most electrical requirements – 100-240/AC
or DC, 24-120/AC or DC, or 12-24/DC. Each coil has built-in
electrical surge suppression that protects the coil from
external voltage spikes and eliminates inductive voltage
spikes associated with conventional solenoids. An optional solenoid
is available for use in Class I, Division 2 hazardous locations.
ASCO RedHat Next Generation addresses many other operating
characteristics that will further improve the life of your
solenoid valves. These include a much lower temperature
rise, and an increase in valve ambient temperature rating to
140˚F/60˚C. Because of our confidence in the rugged design
of the RedHat Next Generation solenoids, ASCO is pleased
to extend a 3-year warranty on the coils.
