1. Product Features (Customizable according to different requirements)
1. Reliable Sealing Performance
Adopts soft sealing design, with the sealing ring closely fitting the valve seat to ensure bidirectional sealing performance, suitable for working conditions with high sealing requirements.
The sealing ring is replaceable and easy to maintain; it can be replaced without disassembling the entire valve, reducing maintenance costs.
2. Easy Operation
Manual operation; the butterfly plate only needs to rotate 90° to complete opening and closing, making operation simple and response fast, suitable for frequent opening and closing conditions.
3. Compact Structure
Small size, light weight, easy to install and carry, especially suitable for installation environments with limited space.
4. Wide Application Range
Suitable for various media, including water, sewage, seawater, industrial wastewater, etc., with a temperature range of -10℃ to 80℃.
5. Strong Durability
The valve body and butterfly plate are made of high-strength materials, with good corrosion resistance and wear resistance, extending the valve's service life.
6. Bidirectional Sealing
Capable of withstanding pressure from both directions, suitable for pipeline systems requiring bidirectional sealing.
