1. Simple structure, small size, light weight, small installation size.
2. The sealing material has two types: soft and hard, which can be used in various working conditions, and has good sealing performance and long service life.
3. The butterfly valve with fireproof structure design can prevent the expansion of fire accidents. Once the soft seat of the butterfly valve catches fire and is damaged, the stainless steel metal sealing ring will play a role to keep the butterfly valve tightly sealed.
4. When the butterfly valve is fully opened, the flow resistance is small, and it can perform sensitive flow control when it is partially opened.
5. The driving torque is small, the operation is simple and fast.
