It can be customized according to different needs

I. Product Features (can be customized according to different needs)
1. Reliable sealing performance
Adopting soft sealing design, the sealing ring and the valve seat closely fit to ensure bidirectional sealing performance, suitable for working conditions that require high sealing performance.
The sealing ring is replaceable and easy to maintain, no need to disassemble the whole valve to replace the sealing ring, reducing maintenance costs.
2. Easy operation
Manual operation, the butterfly plate only needs to rotate 90 ° to complete the opening and closing, easy to operate, fast response speed, suitable for frequent opening and closing conditions.
3.Compact structure
Small volume, light weight, easy to install and carry, especially suitable for limited space installation environment.
4.Wide range of application
Suitable for a variety of media, including water, sewage, seawater, industrial wastewater, etc., the temperature range of -10 ℃ to 80 ℃.
