系列F127W法兰高性能水减压阀适用于以可观的幅度降低输入水压，以保护管道系统部件，降低水消耗。系列F127W是一种远程控制调节阀，特别适用于在减压情况下以最小的压降必须达到全流量的商业和工业应用场合。这个系列也适用于通过大流量时要求进行关闭压力调节的应用。这个系列也适用于水供应压力高达175
psi (12 bars)的应用，调节幅度可以是25 – 100psi (172 – 690kPa)。所有部件都可以迅速容易的维修。
Series F127W Flanged High Capacity Water Pressure
Reducing Valves are designed to reduce incoming water pressure to a sensible
level to protect plumbing system components and reduce water consumption.
The F127W is a remote control type regulator ideal for commercial and
industrial applications where a regulator must reach full capacity with
a minor drop in reduced pressure. This series is also suitable for applications
where close pressure regulation is required through extensive volume demand.
This series is suitable for water supply pressures up to 175psi (12 bars)
and may be adjusted from 25 – 100psi (172 – 690kPa). All parts are quickly
and easily serviceable.

规格说明
Specifications
在主管道供应压力超过60psi (413 kPa)而要求降低到60psi (413 kPa)及以下的地方，其靠近建筑物进口处的水供应管道上应该安装一个水减压阀。洒水龙头和外墙消防栓根据用户的选择可以保留全主管道压力。这种阀门应该配置DN10攻丝开孔，以承接平衡管；还配置一个DN20攻丝开孔，以承接辅助调节阀的低流量需求。这种阀门应该是美国瓦茨调节阀公司系列F127W。
A Water Pressure Reducing Valve shall be installed
on the water service pipe near its entrance to the building where supply
main pressure exceeds 60psi (413 kPa) to reduce it to 60psi (413 kPa)
or lower. Sill cocks and outside wall hydrants may be left on full main
pressure at the option of the owner. The valve shall be equipped with
a 3/8" tapping to receive equalizer piping an a
3/4" tapping to receive auxiliary regulator piping
for low flow requirements. Valve shall be a Watts Regulator Company Series
F127W.
