Highlight: Worm gear actuator driven wafer type butterfly valve
Product introduction:
The center-line soft-sealed butterfly valve is the ideal choice for
conventional butterfly valves in pipeline systems. With its simple
structural design, it achieves a minimal flow resistance
coefficient and near-straight flow characteristics, making it less
prone to debris accumulation during operation. Additionally, its
lightweight construction, convenient installation, and low driving
torque ensure easy operation and maintenance. This valve not only
efficiently cuts off media but also precisely regulates flow. The
actuator supports personalized customization, allowing
configuration of manual, electric, pneumatic, and other driving
forms according to user needs. Meanwhile, it offers diverse
material and sealing ring options, adapting to various media and
complex working conditions to fully balance cost and performance.
Soft-sealed butterfly valves are suitable for working conditions
with temperatures not exceeding 120°C and nominal pressures below
1.6 MPa, widely used in industries such as water supply and
drainage, sewage treatment, food processing, heating and gas
supply, marine engineering, hydropower, metallurgy, energy systems,
and textiles. They are particularly suitable for applications
requiring high bidirectional sealing performance or where valve
bodies are prone to corrosion and rust, effectively ensuring stable
system operation.

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.
