Product Advantage
-PTFE Lug Butterfly Valve seats offer excellent resistance to acids, alkalis, solvents, and corrosive media, making them ideal for chemical processing, water treatment, and corrosive fluid applications.
-Silicone rubber valve discs perform well at both low and medium-high temperatures (typically -20°C to 180°C, depending on the rating). Silicone rubber retains its elasticity even when EPDM or NBR may harden or degrade.
-The high elasticity and compression resilience of silicone rubber ensure a tight seal when interacting with the PTFE valve seat.
-PTFE's non-stick properties make it suitable for applications requiring minimal contamination, such as food, pharmaceutical, and hygiene applications.
-Silicone rubber disc butterfly valve offers greater resistance to ozone, UV radiation, and weathering than many conventional elastomers.
