Features:
- Bodies are machined to high tolerances
- Guaranteed standard dimensions for interchangeability of parts and operator
- Top bushing protects the stem from side thrust of operators which are made of impact and corrosion resistant material
- Special double V-shape of stem seal self-adjusts to protect the stem area for either vacuum or pressure use
- 2-piece body and 1-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 FKM
- The ABZ ring seal on the PTFE seat is a molded part of the seat which 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
- Positive secondary seal eliminates leakage into the stem journal as well as migration of line media behind the seat
- PTFE ring seals are located at top and bottom on all PTFE seated valves
- Stem and body are isolated from the 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 and 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
- The 709 series cannot be used on pipe or flange with an ID less than 2-9/16 in
- Buna-N/FKM stem packing and PTFE O-ring
