Features

• Bodies are machined to high tolerances. Guaranteed standard dimensions for interchangeability of parts and operators
• Top bushings protects the stem from side thrust of operators. They are made of impact and corrosion resistant materials
• Special double V-shape of stem seal self-adjusts to protect the stem area for either vacuum or pressure use
• Two-piece body and one-piece disc/stem makes field replacement of seat and disc/stem 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 of special design so as to contain an o-ring creating 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. Teflon® ring seals are located at top and bottom on all Teflon® seated valves
• Stem and body are isolated from line media by the interference fit of the primary seal created between the disc and seat
• Specially designed disc/stem prevents distortion of disc under high pressure. Thin disc allows for maximum open flow
• Disc edge is individually processed through machining for a smooth edge, providing a bubble tight shut-off and maximum seat life
• Resil-O-Seat™ forms a seal against all standard ANSI 125/150 flanges, gasketing requirements are eliminated
