Operator Options: 5 and 10 position handles, Gear operator, Electric or Pneumatic Actuators		Boot-type seat to encapsulate inner body Alignment notches at bottom of wafer valve Easy seat and disc replacement Four redundant seals Stem design prevents blow-out hazard

MATERIALS
Body - Lug style has drilled and tapped lugs meeting ANSI 125/150 flange standards. Lug body standard with Ductile Iron. Wafer body standard with Ductile Iron also available in Aluminum. Top Plate Standard ISO 5211 - accommodates all types of actuators; handles, gear operators, electric and pneumatic actuators. Disc - Precision machined and hand polished for positive seal with contoured edges for lower operating torque plus increased seat life. A full line of under cut discs, sizes 2"-12", is offered. Designed for maximum product flow. Available in 50 psi and 150 psi at same cost. Comes in Ductile Iron, Aluminum Bronze, 316 Stainless Steel. Disc Screw with Locking Assembly - is made of 316 Stainless Steel. Locking assembly prevents disc screw o-ring distortion. Stem - Machined from 17-4 PH Stainless Steel to eliminate twisting of stem. Gives direct disc control of full or partial product flow. Stem-Seal - A third seal ensuring leak resistance externally or internally for vacuum or pressure service. Matches seat material: Buna-N, EPDM, or Viton®. 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". Seat - The seat fully encapsulates the valve body thereby preventing corrosion of the body or contamination of the flowing product. The only wetted parts are the seat, disc and disc screws. Seats are available in EPDM(food grade), black Nitrile (food grade), white nitrile, silicone and Viton®. 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. O-Seal - Two 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. Matches seat material except for silicone. Flange Seal - Sealing O-Ring of resilient seat which provides an absolute seal to all flanges within specifications. No other gaskets required.
