Model 127W
High Capacity Water Pressure
Reducing Valve
Size: 3" (80mm)
Model 127W High Capacity Water Pressure Reducing Valve is
designed to reduce incoming water pressure to a sensible level
to protect plumbing system components and reduce water consumption. The 127W 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
model is also suitable for applications where close pressure regulation is required through extensive volume demand. This model
is suitable for water supply pressures up to 175psi (12.1 bar) and
may be adjusted from 25 – 100psi (172 – 690 kPa). All parts are
quickly and easily serviceable.
3" (80mm) 127W
Features
•  Replaceable stainless steel seat
•  Outstanding maintenance features
•  Close control of reduced pressure
6", 8" or 10"
(150, 178, or 200mm)
depending upon reduced
pressure range.
•  High temperature-resisting diaphragm
•  Interchangeable diaphragm chamber
•  Bronze body construction
Specifications
High
temperature-resisting
diaphragm.
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" (10mm) tapping to receive equalizer piping and a 3⁄4" (20mm) tapping to receive auxiliary regulator piping
for low flow requirements. Valve shall be a Watts Model 127W.
Requirements of various
pressure conditions can be
quickly met by
interchanging the various
sizes of diaphragm chambers - 6", 8", 10"
(150, 178, 200mm)
as well as by interchanging
spring.
Diaphragm chamber
is easily changed by
the removal of
two cap screws.
Stainless steel stem.
Replaceable
stainless
steel seat.
