Advantages of RPTFE sealing ring for high-performance double eccentric butterfly valve
RPTFE high-performance double eccentric butterfly valve seal ring is a kind of enhanced high-temperature RPTFE formula, and the product color is black PPL seal ring can not meet the expected use requirements in the high temperature of high-performance double eccentric soft seal butterfly valve, so we have developed this high-temperature resistant RPTFE formula in repeated practice. To distinguish it from the ordinary RPTFE formula, it is named carbon fiber RPTFE. In years of practical application, the (carbon fiber RPTFE) high-performance double eccentric soft sealing butterfly valve seal ring has been recognized by customers. The new sealing material developed by the high-performance double eccentric butterfly valve RPTFE seal ring to replace the PPL application scenario can replace the imported double eccentric butterfly valve High performance butterfly valve The problem was solved after the carbon fiber RPTFE product was used instead of the PPL product used by several customers in high temperature conditions.

Carbon fiber high-performance double eccentric butterfly valve RPTFE seal ring has the following two advantages:
1. The high-temperature stability of the product is much better than that of PPL material, whether it is the linear expansion coefficient of temperature or the performance of temperature pressure curve.
2. The mechanical property of the product is much better than PPL material.

High performance carbon fiber RPTFE double eccentric soft seal butterfly valve The sealing ring has the advantages of wide applicable temperature range, excellent corrosion resistance, small friction coefficient and good plasticity. It is used in 150LB and 300LB series butterfly valves. The RPTFE sealing ring of high-performance double eccentric butterfly valve is designed to make the medium pressure conducive to sealing. When there is no pressure, the torque transmitted from the valve stem creates enough sealing pressure between the butterfly plate and the sealing ring, Make the valve sealed. When subjected to the positive medium pressure in the pipeline, the sealing ring can be tightly pressed on the sealing surface of the butterfly plate with the aid of the medium pressure in the pipeline, making the sealing performance more reliable. When the medium flows in the opposite direction, the medium pressure acts on the other side of the sealing ring, and the sealing ring will deform in the opposite direction, forming a sealing specific pressure against the butterfly plate sealing ring to prevent medium leakage.
