410SS Stem Material Industrial Butterfly Valve Zero Leakage Triple Offset Butterfly Valve

Triple Offset Butterfly Valve , Inch 2"-60" Class150-600Carbon steel, Stainless steel, Duplex stainless steel

Zaval Double Offset Butterfly Valve is design offers rugged reliability and extremely easy maintenance in the field. These valves are Bi-directional with zero leak features. Resilient seat design also can achieve low torque which is easy for operation.Zaval High Performance Valve delivers the highest quality and highest value available for meeting today’s demanding requirements of zero leak.

Triple Offset Frictionless Design

1st offset: The stem shaft is offset from the sealing surface plane, allowing for a continuous engagement of the seating surface.
2nd offset: The stem shaft’s rotation axis is offset from the center of the bore, removing contact between the seat and the seal ring through most
of the disc’s travel.
3rd offset: The conical seating surface is offset asymmetrically to eliminate friction during opening and closing.
