|Actuator Type||Butterfly Valve(≤PN1.0MPa)||Ball Valve(≤PN1.6MPa)||Vent Valve(≤PN0.1MPa)|
DCL concentric soft seal butterfly valves are widely used for Commercial Heating & Air Conditioning, Wastewater & Water Treatment, Seawater/Desalination, Food & Beverage Processing, Pulp & Paper Processing, oil & gas etc.
NBR seat is always used for oil related medium.
EPDM is the most commonly used material with medium temperature ≤ 200℃.
PTFE seat is always used for high temperature medium that is ≤ 300℃, and also has the best chemical stability.
