Worm gear actuator driven wafer type butterfly valve

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.
