valve seat

Jiashan Itaflon Fluorine Technology Co., Ltd. provides Hyperfloat for valve seats ® Hyperion series filled modified PTFE materials. Yidelong filled modified PTFE material has excellent performance, effectively solving the rebound problem of valve seat pressure. It can be applied to various high-temperature corrosive chemical fluids and solvents. Its low swelling ability can maintain sealing performance for a long time, and the temperature range can be from refrigerant to 300 ℃. The pressure per unit area can reach 700kg, and the movement speed can reach up to 20m/s.

Advantages of Yidelong Valve Seat Material
1. Low friction coefficient
2. Low coefficient of thermal expansion
3. Excellent resilience
4. Excellent creep resistance under high pressure
