ARI – ZETRIX® Triple Offset Butterfly Valve

The ZETRIX® triple offset butterfly valve is an isolation valve with reliably tight metal-to-metal sealing. The self-aligning laminar seal ring, in combination with the triple offset geometry, results in a design that can provide bidirectional, bubble-tight shutoff. Available in double flanged, fully lugged, and butt weld design configurations.

PRODUCT DESCRIPTION:

Reliably tight – even in toughest industrial environments

  • Due to the triple offset disc design (maximum closing force with minimum effort).
  • Due to the “smart” sealing ring (uniform closing force, the ring is self-aligning and free-floating on the sealing surface).
  • Due to a wide range of additional safety options.
  • Due to the stellited seat (Stellite™ No. 21) as standard version.
  • Due to the metal seal principle.

Durability

  • Long and maintenance free service life due to the stellited seat.
  • Rotary movement without wear or friction (seat and sealing ring) due to the optimized contact angles.
  • Hardened stainless steel bearings.
