Resilient seated butterfly valve is a Double Flanged design which can be used for dead-end service. This butterfly valve series has many of the design features and benefits , such as high Cv ratings, minimum parts exposed to the line media, greater reliability and a proven record of long service life. A major design advantage of this valve product lines is international compatibility.

A double flanged valve in short construction designed for heavy duty services.
Highlight:
¡¤Less deformation of the liner from vulcanized liner
¡¤No deformation of the liner between the flanges during assembly
¡¤All AVANNTO valves are pressure tested to 110% of rated pressure to assure bubble tight shutoff.
¡¤All AVANNTO butterfly valves are pin-less design
¡¤Internal disc-to-stem connection
¡¤ISO 5211 international compatibility
¡¤Direct mount all AVANNTO actuators including handles, gear operators, pneumatic and electric actuators
