ЗДП triple offset butterfly valve

 

Triply-eccentric (offset) design 

Triple eccentric (offset) Design prevents galling and scratches between the metal seat and the metal disc due to its unique design. The only time where the seal comes into contact with the seat is at the point of complete closure. Triple offset valves are generally used in applications which require bi-directional tight shut-off in oil and gas, LNG/NPG terminal and tanks, chemical factories, and shipbuilding. Widely use for dirty/heavy oil to prevent extrusion.
