Highlight: Worm gear actuator driven wafer type butterfly valve
Product introduction:
Middle-line soft seal butterfly valve is the preferred conventional
butterfly valve for pipeline. The utility model has the advantages
of simple structure, small flow resistance coefficient,
near-straight flow characteristics, and is free of debris, in light
weight, convenient to be installed, and small in driving torque.
This valve can be used to cut off media and also to regulate the
flow of media used. Its actuating device can be made according to
user's requirements, either in manual, electric, pneumatic, or
other forms. Different materials are selected and seal rings of
different materials are provided. The valve is applicable to
different media and working conditions and makes the cost and
performance to achieve the best match. The soft seal butterfly
valve is suitable for the temperature lower than 120℃ and nominal
pressure lower than 1.6 MPa,and it is suitable for the industries
such as water supply and drainage, sewage, food, heating, gas,
shipping, hydro-power, metallurgy, energy system, and
textile,particularly suitable for two-way seal box valve bodies
that are easy to be rusted.

Product features:
1. Compact and portable, easy to remove and maintain, and can be
installed at any position;
2. Its flow characteristic tends to be straight line and it is of
great regulating performance;
3. Simple structure, compact, small operating torque and fast
opening by only rotating 90 degrees;
4. Internal leakage point is eliminated by connecting valve plate
with valve rod without pin;
5. The encircle of valve plate is made as ball to improve the
sealing performance and prolong the service life of valve, and
there is zero leakage after the valve has been opened and closed
for 50,000 times under pressure;
6. Sealing element can be replaced, and suitable for two-way seal
box.
7. The butterfly disc can be painting as the request.
8. The valve can be flange or the wafer.
9. The motivation can be the handle, pneumatic and electrically
operated valve.
