ABZ 709 Resilient Seated Butterfly Valve
Features:
- All bodies are machined to tight tolerances which guarantees standard dimensions for interchangeability of parts and operators.
- Top bushing protects the stem from side thrust of operators. They are made of impact and corrosion resistant materials.
- Special double V-shape of stem packing seal self-adjusts to protect the stem area.
- Two-piece body and one-piece stem/ disc makes field replacement of seat and stem/disc quick and easy.
- The special snap-in Resil-O-Seat™ design secures seat in place without bonding. The Resil-O-Seat is 100% field replaceable - no special tools required. All standard seats are Food Grade with the exception of Viton™.
- The ABZ Ring Seal on the Teflon® seat is a molded part of the seat. It is a special design containing an o-ring which creates a positive seal around the stem as well as between the seat and valve body. This positive secondary seal eliminates leakage into the stem journal as well as migration of line media behind the seat.
- Stem and body are isolated from line media by the interference fit of the primary seal created between the disc and seat.
- Specially designed stem/disc prevents distortion of disc under high pressure. Thin disc profile allows for maximum flow.
- Disc edge is individually processed through machining and buffing for a smooth edge. This provides a bubble tight shut-off and maximizes the life of the seat.
- Resil-O-Seat forms a seal against all standard ANSI 125/150 flanges. Gasketing requirements are eliminated.
