特别适用于保护旅行拖车的水罐
Especially Designed to Protect Water Tanks in Travel
Trailers
美国瓦茨H560G竭尽全力设法解决当压力达到40psi时能够自动关闭流出的水以便补充装满用户的水罐。这种阀门特别适用于配置自带水供应容器的旅行拖车和旅行车，标准配置为DN20的NH软管连接，便于方便的连接到拖车停车场或野营场地的供水设备。
Watts H560G takes the worry out of replenishing
your water tank by automatically turning the water off when pressure reaches
40psi. These valves are especially designed for travel trailers and recreational
vehicles, with self-contained water supply tanks, and are standardly furnished
with 3/4" NH hose connections to permit convenient
attachment to trailer park or camping ground supply fixtures.
作为一个附加的性能，适用于非永久性或过夜安装，这种阀门还能够根据需要自动将水供应到容器内，因此避免人工注水和接管，减少水泵或压缩机的磨损和划伤。
As an added feature, for semipermanent or overnight
installations, the valve will also supply water automatically as needed
to the tank thereby eliminating manual filling and pumping, and saving
wear and tear on the water pump or compressor.
与用于拖车上的其它品牌的调节阀不同，型号H560G可以调节到更高或更低的压力，可以拆开进行清洗或维护（流过任何调节阀的水可能会在阀体内淤积沉淀物，迫使阀门必须进行清洗和维修）。虽然其它在线调节阀运行很好，但是它们却没有清洗和维修的重要功能。这就意味着当这种调节阀积满沉淀物后，这种装置就必须通过购买新的来更换；而型号H560G则可以拆开，进行清洗，重新调节，然后重新安装运行。因此，可维修性所带来的方便使得服务期限更加长。
Unlike some other brands of regulators for trailer
application, H560G can be adjusted to higher or lower pressures and can
be taken apart for cleaning or maintenance (water flowing through any
regulator can build up sediment within the valve body making it necessary
to clean and service). Even though other in-line type regulators work
well, they do not offer the important feature of cleaning and servicing.
This means when such a regulator becomes filled with sediment, the device
must be replaced by buying a new one; whereas H560G can be taken apart,
cleaned, readjusted and then put back in service. Therefore, the convenience
of being serviceable affords longevity of service.
外形紧凑，成本经济，美国瓦茨型号H560G对于保护每一辆旅行车和家庭拖车是必要的装置。
Compact in size and economical in cost, Watts
H560G is necessary protection for every recreational vehicle and home
trailer.

 型号H560G压力调节阀配置0-60psi压力表。
Model H560G
pressure regulator furnished with 0-60psi gauge.
型号H560仅是调节阀，没有配置仪表。
Model H560
is regulator only, less gauge.
最大供应压力: 150psi，包括可以容易的拆卸进行清洗的整体过滤器。
Maximum Supply Pressure:
150psi Contains integral strainer which is easily removed for cleaning.
可调节减压范围: 10-60psi
Adjustable Reduced Pressure Range: 10-60psi
如果要重新调节压力，则松开锁进螺母，顺时针旋转调节螺丝，提高减压；逆时针旋转，降低减压。
To readjust reduced pressures, loosen check nut
and turn adjusting screw clockwise to raise reduced pressure and counterclockwise
to lower reduced pressure.
安装
Installation
建议的安装位置（如图所示）是将水调节阀连接到消防栓上，然后再通过软管连接到拖车上。这样既保护拖车系统，也保护软管。此外，如果调节阀直接连接到拖车上，然后再将软管连接到消防栓上，则软管就没有得到保护，可能会需要昂贵的更换。然而，重要的是连接到调节阀出口端的软管供应端上的第一个螺丝要采用管钳将其紧固到软管接头上，使其几乎无法用手拆卸。通过这个方法，在离开和卷起软管时，调节阀将成为软管上的永久性部件而不需要多操心了。
The recommended location (as shown) is to connect
the water regulator to the hydrant, and then run the hose to the trailer
rig. This gives protection to both the trailer system and the hose. Otherwise
if the regulator is connected directly to the rig and then the hose run
to the hydrant, the hose gets no protection and is expensive to replace.
However, it is important to first screw the supply end of the hose to
the outlet end of the regulator using a pipe wrench to tighten it onto
the hose coupling, making it almost impossible to remove by hand. In this
way when leaving and rolling up the hose, the regulator won't be forgotten
because it has become a permanent part of the hose.
