Highlight: Worm gear actuator driven wafer type butterfly valve
Product introduction:
The center-line soft-sealed butterfly valve is the preferred
conventional butterfly valve for pipeline systems. It features a
simple structure, low flow resistance, and minimal debris
accumulation, ensuring smooth media flow. With its lightweight
design, easy installation, and low driving torque, it significantly
reduces installation and maintenance costs. In terms of
functionality, it can both cut off media and flexibly regulate
flow, meeting diverse industrial requirements.This valve offers
flexible configurations, with actuators available in manual,
electric, pneumatic, and other forms. It also provides multiple
choices for materials and sealing rings, enabling adaptation to
complex media such as acids, alkalis, and corrosives, as well as
harsh working conditions. This balances performance and cost
effectively.Soft-sealed butterfly valves are suitable for working
conditions with temperatures up to 120°C and nominal pressures
below 1.6 MPa. They are widely used in industries such as water
supply/drainage, food processing, and energy, particularly in
scenarios requiring high bidirectional sealing or resistance to
rust. They serve as a reliable guarantee for 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.
