<p>A Superior Sanitary Valve for the Chemical and Food Processing Industry </p> <p><strong>Top Plate: </strong> </p> <p>Machined to standardized drilling patterns allowing manual handle kits, and actuation, interchangeability standard with ISO patterns </p> <p><strong>Stem Bushing: </strong> </p> <p>Composed of full strength, corrosion resistant ertalyte, stem bushings absorb operator side thrust. </p> <p><strong>Stem-Seal: </strong> </p> <p>A third seal ensuring absolute seal externally or internally for vacuum or pressure service. </p> <p><strong>O-Seal: </strong> </p> <p>Two Sure Seal 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. O-seals are also located at top and bottom of stem entry to form an absolute secondary seal. </p> <p><strong>Hub Seal Or Primary Seal: </strong> </p> <p>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. </p> <p><strong>Body: </strong> </p> <p>Lug style has drilled and tapped lugs meeting ANSI 125 and 150 flange standards. Two-piece body allows ease of seat replacement. Lug body standard with ductile iron or 25-5 stainless steel. </p> <p><strong>Flange Seal: </strong> </p> <p>Sealing O-ring of resilient seat which provides an absolute seal to all flanges within specifications </p> <p><strong>Disc/Stem: </strong> </p> <p>Sure Seal?s standard is 25-5, a duplex stainless which is more corrosion resistant and almost twice as strong as all other butterfly valve manufacturers? standard 316 stainless steel. This eliminates shaft twisting and water hammer damage and allows a thin disc design which increases CV rating without reducing strength. All encapsulated disc stems are 25-5 duplex stainless as standard which gives you approximately four times the corrosion resistance as 316 stainless steel and more strength too. </p>
