Product Details
Low Torque Operation Resilent Seated Gate Valve, Suitable For Water
Description:
Gate valve is a resilient seated NRS gate valve, DI body and
bonnet, EPDM rubber wedge,bronze nut, SS420 stem, cap or hand wheel
opeerated,PN10,PN16,PN25.
Feature:
1. Stem sealing
Stem sealing replaceable under pressure with three independent stem
seals:
NBR wiper ring protects against dirt from outside.
4 pcs of O-ring protects the stem and prevents leakage.
Replacing stem seals under pressure is available.
2. Vulcanized wedge
The ductile iron core is fully vulcanized with drinking water
approved EPDM rubber internally and externally. No iron parts are
exposed to the medium and the excellent rubber vulcanization
prevents corrosion underneath the rubber. Nylon Guides in the wedge
and on the valve body ensure a uniform closure regardless of high
pressure.

Company Profile
Alpine Flow Control (SuZhou) Co.,Ltd with major focus in the water
valve design and manufacturing. The Management staff have over 30
years experience in the water valve design and manufacturing,
combined with the high-tech electronics manufacturing experience of
multi-national listed companies. This unique combination of
traditional and high-tech industry management experience and skills
have given us an advantage over the traditional valve manufacturer.
More than 40% of our staff are technical staff with knowledge and
experience in valve and mechanical design/manufacturing...
Proven and supported by on-going quality and reliability test. AFC
has built it’s own in house reliability test laboratory to ensure
that our products not only meet the international quality and
reliability test specification such as the EN-1074-1/2 T-key and
R-key test, but also comply to various international valves
standards and specifications.
We already achieved WRAS certificate in 2011, and obtained FM
approval in early of 2012,
and UL for gate valve. Today, we have got many international famous
certificate for drinking water such as WRAS, NSF, AS, CE on certain
products, and our product range has expended to double eccentric
butterfly valve, rubber disc check valve ,non-slam check valve,
both clean water & sewage water air valve, hydraulic control
valve and penstock and we always focus on water system valves.
In 2018 year, our big plan is developing pressure management valves
which has been proved to be a very helpful tool and economic way to
save the leakage rate with limited investment and get a fast return
in couple months and power savings
In addition, we have a special project team to focus on custom
design and special requirement
