Catridged seat butterfly valve

Cartridge Design Seat

Elastomer is supported by hard phenolic backing which eliminates seat shifting during installation.
Seat to disc seal is independent of flange support and capable of full rated dead end service.
Static seat design allows disc to sweep into seat for lower and more consistent torque.
Smaller mass of elastomer minimizes seat swell.
