SureSeal Butterfly Valves
Series 500-522 
Stem – Machined from 17-4 Stainless Steel to eliminate twisting of stem, giving direct control of full or partial product flow
Top Plate – Machined to standardized drilling pattern allowing manual handle kits, and actuation, interchangeability also available in ISO patterns
Stem Bushing – Composed of full strength, corrosion resistant ertalyte, stem bushings absorb operator side thrust. Top bushing comes standard in all valves, while bottom bushing comes with all valves sizes 4”-12”.
Stem-Seal – A third seal ensuring absolute seal externally or internally for vacuum or pressures service. Available in Buna-N, EPDM, or Viton.
O-Seal (patented) – Two SureSeal O-Seals give a sure secondary seal as the O-seal becomes part of the body and encircles the stem before entering the seat and disc area. Available in Buna-N, EPDM, Viton, or Teflon.
Seat – EPDM, Viton, and SureSeal’s Special Abrasion Resistant formulated blend of FDA approved Nitrile, along with 12 other standard compounds to meet your application.
Hub Seal or Primary Seal – Occurs when contact is made between the disc hub and the flat surface of the seat. Hub/seat seals prevent product from attacking stem or body.
Body – Lug style has drilled and tapped lugs meeting ANSI 125 and 150 flange standards. Wafer body standard with Cast Iron also available in Aluminum, Anodized Aluminum, Aluminum Bronze, Stainless Steel, Teflon Coated and several Corrosion Resistant platings.
Disc Screw and (patented) Sure Lock Assembly – Made of 316 Stainless Steel, the Sure Lock should be replaced anytime valve is disassembled and reassembled.
Flange Seal – Sealing O-Ring of resilient seat, which provides and absolute seal to all flanges within specifications.
Disc – Precision machined and hand polished for positive seal with contoured edges for lower operating torque plus increased seat life. Comes in Nodular Iron, Aluminum Bronze, 316 Stainless Steel, Monel, 255, 254-SMO, and also specially coated and plated discs for special applications.
