1. Seal with elastic metal steel in the interlayer enables the valve to have zero leakage performance.
2. The friction-free design of right-angle rotation is realized by a unique triple offset design. There is no friction between the seat and seal ring when the valve opens from 0 to 90 degrees, which eliminates the possibility of wear and leakage and prolongs the service life of the valve.
3. Torque seal can meet the requirement of two-way zero leakage in the long-term operation of the valve. The switch life of the valve allows five hundred thousand times.
4. An all-metal structure with zero leakage performance makes the valve has essential fire safety characteristics.
5. The butterfly valve adopts a precision casting process, including the body and the disk. This process has many advantages compared to the steel plate coiling process, the most important of which is that the overall strength of the valve is high, and the cost of it is also higher than that of the coiling process.
6. The external blow-out-proof stem is safe and reliable and complies with the requirements of API 609.
