Why are the new ProPEX EP
valves better than standard
ball valves?
The new EP valves feature the
proven performance of engineered
plastic and the durability and
precision of ceramics. They resist
chemical and mineral buildup,
along with corrosion, pitting and
scaling. Unaffected by aggressive
water, the valves provide superior
gpm performance and address all
ANSI/NSF Standard 61 lead-
content initiatives. (See Figure 1.)
What is the benefi t of ceramics?
Ceramics are often referred to
as having a “polished diamond-
hard surface” that translates into
smoother operation. Ceramics
are also resistant to hard and
aggressive water conditions that
contain mineral deposits that can
damage other material surfaces.
Ceramics are designed to operate
effi ciently without the use of
washers that are found in other
valves. In short, ceramics are
a highly durable product that
deliver consistent, long-lasting
performance.
Where can ProPEX be used?
EP valves can be used for PEX-
to-PEX and point-of-use shut-off
at the fi xture. The stop valves
come in angle- and straight-stop
confi gurations for ½" Wirsbo
AQUAPEX tubing; the in-line
valves are designed for ½" and ¾"
Wirsbo AQUAPEX tubing.
Can these valves be used in any
type of construction?
The quality, durability, design and
testing results of these valves
prove they can be used in any
building type.
What can the installer save
by using these new valves?
The new valves provide more stable
material costs when compared to
brass. Through better, longer and
more reliable performance, they
save money in the long run.
Why EP and not brass?
With more than one million Uponor
EP fi ttings in service to date, EP is
proving to be superior over brass
and will not pit or corrode like
brass can in harsh environments.
Can EP valves handle the same
pressure as brass valves?
EP valves are put through the same
rigorous testing as brass valves.
Both are capable of handling burst
pressures up to 500 psi.
Why are EP Valves biscuit
in color?
This neutral biscuit color was
chosen for its ability to optimize
interior design choices.
FAQs for ProPEX EP Stop and In-line Valves
Uponor’s new ProPEX EP Stop and In-line
Valves Feature Ceramic-disc Technology
Uponor’s new, unique valve design features the proven
performance of Uponor’s engineered plastic (EP)
combined with the durability and precision of ceramics.
This exclusive ProPEX series of both In-line Valves for
PEX-to-PEX applications and Stop Valves for point-of-
use shut-offs at the fixture offer all the installation and
performance advantages you’ve come
to expect from Uponor products
(patent-pending).
1. These new ProPEX
valves greatly enhance
gallons per minute
(gpm) performance,
as compared with
standard compression
stem and bonnet-
stop valves.
2. Unaffected by
aggressive water,
they are designed to
resist the chemical and
mineral buildup that can
restrict gpm, providing
corrosion-free, non-pitting and
non-scaling surfaces that result in
long-term use that is not possible with brass.
3. In addition, these ProPEX valves address all ANSI/NSF
and state lead-content initiatives.
Featuring all ProPEX connections, these valves offer
one more great advantage to using Wirsbo AQUAPEX®
tubing and its unique ProPEX fitting systems for all
residential and commercial applications.
