S200-0504 Rubber Seated Butterfly Valve Series 100/200 401 S. Highland Avenue Aurora, IL 60506 Phone: 877-436-7977 Fax: 630-844-4124 www.henrypratt.com Construction Specifications: Sizes: 2" through 48" Body: Cast Iron — Wafer or Lug* Disc: Ductile Iron Epoxy Coated Stainless Steel Aluminum Bronze Stem: Stainless Steel Resilient Seat: EPDM BUNA-N Viton Actuation Options: Worm Gear Pneumatic Pressure Ratings: 2"-12" — 175 psi 14" and larger — 150 psi *for installation between ANSI Class 125 flanges Features: ■ All cast body machined to high tolerances. Guaranteed standard dimensions for interchangeability of parts and actuators. ■ Shaft bushings are impact and corrosion resistant materials. Protects the shaft from side thrust of actuators. ■ Special double-V-shape of stem seal self-adjusts to protect the stem area for either vacuum or pressure use. ■ Stem and body are isolated from line media by seal created between disc flats and flat surface of seat. ■ The special snap-in Resil-O-Seat design fixes seat in place without bonding. The Resil-O-Seat is 100% field replaceable — no tools required. ■ Molded O-ring in the Resil-O-Seat forms a seal against all standard flanges. Gasketing requirements are eliminated. ■ Disc edge is machined and buffed, providing a bubble tight shutoff and maximum seat life. ■ All valves are factory tested at their rated pressure.
