Shenyang
Special Butterfly Valve Factory is
specialized in producing butterfly
valves for export in China. It has
rich experience in the design, manufacturing
and testing of products and was approved
to be appointed production enterprise
of metal airtight butterfly valve
and soft airtight butterfly valve
of anti-severe corrosion series of
butterfly valve after checked by
the Appraisal Committee for Appointed
Production Enterprise of China Architectural
Metal Structure Association Water
Supply & Drainage Equipment Branch
under the Ministry of Construction.
It enjoys good reputation in the
field.
Shenyang Special Butterfly Valve
Factory mainly produces middle and
low-pressure valves and its main products
are soft airtight series of butterfly
valves with symmetrical direct-plate
solo eccentricity, double eccentricity
structure, and metal hard airtight
series of butterfly valve with tri-eccentricity
structure. The connecting formats include
butt clamp and double flange, DN32-2000mm
and PN0.1-2.5Mpa, driving measures
include manual operation, gear driving,
pneumatic driving and electric driving.
In addition, we produce back valve,
adjusting valve, balance valve, brake
valve, isolating valve, diaphragm valve,
expansion bend and gate lifter, etc.
over ten series. Of them our independently
developed double eccentricity series
of butterfly valve won the silver award
in the 11th National Invention Expo,
and Flow Lock-in Valve and Metal Hard
Airtight Butterfly Seal Ring obtained
two national patents in 1997 (Patent
Numbers: 972334510. 3 and 97233450.1).
In order to expand the factory, our
factory and Shenyang Hengyi Industrial
Co., Ltd. set up close-type enterprise
group to explore international market
together. We also imported Germany
ARI high-pressure valve to promote
domestic valve field to develop towards
high quality and brandilization.
Recently we succeeded developing
anti-severe corrosion series of butterfly
valve with international advanced painting
technique (SEBF fusion resin). This
series of butterfly valve solved the
problems of poor painting adhesion,
easy aliquation and dropout, low anticorrosion
property existed in the former ordinary
anticorrosion butterfly valves. SEBF
painting is featured for its good stability,
anticorrosion of such media as acid,
alkali and saline. To adopt whole painting
will solve the problem of seam leakage
corrosion. It is available to replace
stainless steel or titanium alloy with
ordinary carbon steel as valve basis
material for the advantages of reducing
equipment investment, strong adhesion
and adhesive strength can reach 90Mpa,
which is not reachable for ordinary
lining rubber and plastic, strong antifriction,
much suitable for petrochemical system
and sewage treatment fields working
in the condition of high temperature
and strong corrosion.
Since foundation, our factory
keeps developing in fierce market competition.
Relying on strong technical strength,
perfect inspection and test measures,
strict quality assurance system and
well-trained personnel team, we have
provided first-class products and sound
service to broad customers at home
and abroad. Our factory was appraised
as "Quality Credit Assurance Unit", "Quality
Tracing Unit" and "AAA Grade
