标准性能
Performance is standard
每个美国瓦茨自动控制阀所结合的结构和创新上的新特性，进一步强化了一致性，可靠性，高性能，积极控制和更长的使用寿命。
The design and innovative features incorporated
into every Watts Automatic Control Valve means consistent, dependable,
high performance, positive control and long life.
高效的结构
Efficient design
主阀，截止阀或角阀结构，采用隔膜驱动，液压操作。仅仅包含四个主要部件。阀体，阀盖，加上内部阀座和隔膜/阀杆总成。隔膜/阀杆总成是主阀内唯一的活动部件。
The main valve, globe or angle pattern, is diaphragm
actuated, hydraulically operated. It consists of only four major components.
The body and cover plus interior seat and diaphragm/stem assembly, which
is the only moving part in the main valve.
可变容积阀盖腔
Variable volume cover chamber
合成橡胶/尼龙隔膜，美国食品及药物管理局认证的材料，组装在阀体和阀盖内。这就产生了一个密封的腔室，导入管线流体和压力。压力的变化将精确定位阀杆总成，使得阀门实现所要求的启、闭或调节的操作。
A synthetic rubber/nylon diaphragm, of FDA approved
materials, is assembled between the valve body and cover. This creates
a sealed chamber into which line fluid and pressure is introduced. Varying
the amount of pressure accurately positions the stem assembly to open,
close or modulate the valve as required.
精确定位和稳定节流
Precise alignment and stable throttling
阀盖轴承和整体阀座轴承引导阀杆总成，实现与阀座的精确定位。加上四边形密封护圈板，这种对齐定位确保逐级的启/闭流量，稳定的节流，低摩擦操作和积极的关闭。
A cover bearing and integral seat bearing guide
the stem assembly for precise alignment with the seat. Coupled with the
quad seal retainer plate, this alignment assures progressive opening/closing
flows, stable throttling, low friction operation and positive closure.
不透水密封
Drip tight seal
美国瓦茨ACV第一个采用动态四边形密封，在自动控制阀领域处于领先地位。阀座、3.5边上的护圈，提供积极关闭性能，因此不再需要“啮合”进阀座内，从而延长了阀门的使用寿命。每个四边形密封都有两个可用的边。
Watts ACV leads the automatic valve industry by
being the first to incorporate the dynamic quad seal. The seat, retained
on 3 1/2+ sides, provides positive closure while eliminating the need
to “bite” into the seal, adding years to the valve’s life. Each quad seal
has two usable sides.
熔融环氧树脂涂层，延长使用寿命
Fused epoxy prolongs life
这种涂层是在严格的预备和应用标准下进行涂敷的。它是不能渗透的，能够改善阀门的流量系数，将铸件与所控制的流体有效地隔开。这种涂层还能够保护阀门免受环境的侵蚀。图层表面能够防止矿物质的累积和铁锈（导致控制阀故障的主要因素），简化维护保养，延长阀门的使用寿命。
This coating is applied under rigorous preparation
and application standards. It is non-porous, improving the flow coefficiency
of the valve and effectively sealing the casting from interaction with
the controlled liquid. The coating also protects the valve from environmental
attack. The finish prevents mineral buildup and rust (a major factor in
control valve failure), simplifies maintenance, and prolongs the life
of the valve.
多种性能
Multiple function performance
通过改变控制/管线对齐，美国瓦茨ACV能够实现多种功能和应用。多种性能集成在一个阀门上使得系统得到更多的保护，也降低了用户的成本。
By varying the control/piping arrangement, the
Watts ACV is able to perform a diversity of functions and applications.
Multiple functions performed by a single valve can result in added system
protection and lower cost to the user.
简化维护
Simplified Maintenance
不需要从管线上拆卸阀门，就可以对主阀和引导系统进行维修。
The main valve and pilot system can be serviced
without removing the valve from the line.
正确的阀门，正确的位置，正确的时间
Right valve, Right place, Right time
美国瓦茨ACV致力于为用户提供正确的性能和材质的阀门，以满足用户的应用要求，并为这些阀门的精确性和严格按照计划的交货期而感到自豪。
Watts ACV is committed to providing you with correct
function and material to meet your application requirements and prides
itself with accurate, calculated delivery schedules. |
