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.
