Resilient Seated Series CI-1000 Butterfly Valves
(2"-24" Butterfly Valve)
(26"-40" Butterfly Valve)
Features:
- Stem connection available in standard VALTORC sizes or optional sizes to match standard secondary top plate drilling.
- Top plate double drilled to fit ISO 5211 dimensions and standard secondary bolt circle dimensions. All handles, gear operators and pneumatic VALTORC actuators are designed to mount directly to VALTORC Butterfly Valves.
- Nylon PA 12 coated disc option ensures excellent corrosion resistance to several chemical media. The hard, nonporous sintered polymer has very low hygroscopicity and is suitable for use in drinking water and nonalcoholic foodstuffs.
- Two flange Butterfly Valve locating holes for sizes up to 12” and four flange locating holes from size 14” to 24” for easy alignment of valve during installation. They m eet ANSI #125/150 or other world drilling standards.
- Precision machined radius on the upper and lower disc hubs on this Butterfly Valve is pressed against upper and lower seat sealing faces for achieving primary sealing between disc and seat.
- Heavy duty square-grooved seat design with molded O-ring seals to serve as flange gaskets. EPDM seats are peroxide cured to yield the best elastic properties of the elastomer.
- High performance Butterfly Valves
Industrial Split Body Butterfly Valves Series 1100
Features:
- One-piece disc/stem in high strength Butterfly Valve design. Available in options such as 316 stainless steel (thin profile, with hand polished edge and hubs), PTFE, Nylon 12 Coated 316 SS or rubber covered with the covering extending on the stem in the sealing area.
- Precision machined radius on the upper and lower disc hubs is pressed against upper and lower seat sealing faces for achieving primary sealing between disc and stem.
- Bi-directional “U” cup stem seal.
- Two flange locating holes for sizes up to 12” for easy alignment of valve during installation.
- Butterfly Valves meet ANSI#125/150 or other world drilling standards.
- Heavy-duty acetal bushing absorbs the forces acting on the stem/disc assembly due to line pressure.
- Unique heavy-duty, square grooved “Center Lock” seat design virtually eliminates any seat movement during the seating and unseating of the disc.
Double Eccentric High Perormance Butterfly Valves Series 1200
Features:
- The Butterfly Valves top flange is drilled as per EN ISO 5211 to accommodate direct mounting of a wide range of actuators.
- One-piece wafer body style or full lug style for dead end service. Both Butterfly Valve body styles offer bidirectional sealing as standard in conformance with full ASME class 150 and class 300 rating.
- Butterfly Valve Pins are offset from the center of the stem which places them in compression rather than shear thus eliminating potential for failure. The pins are precision fit and wedge types which provide positive mechanical attachment of disc to stem.
- The disc stop is a machined position stop on the body that locates the disc in the seat to achieve maximum seat and seal life. The disc stop is designed to prevent disc from rotating in to the wrong direction and minimizing possible seat damage.
- The unique Butterfly Valves seat design utilizes a flexible lip seal concept When the disc closes, this action causes a slight deflection in the seat, energizing the seat.
High Flow Resilient Seated Butterfly Valves Series 1300
Features:
- Four flange locating ribs for sizes up to 12” and four flange locating holes from size 14” to 24” for easy alignment of valve during installation. They meet ANSI #125 /150 or other world drilling standards.
- Unique stem retention system to provide blow-out proof stem and easy assembly and disassembly of the Butterfly Valve.
- Heavy duty one-piece body Butterfly Valve. Standard coating is two coats of hard, zinc-rich epoxy for excellent corrosion resistance.
- Precision machined radius on the upper and lower disc hubs is pressed against upper and lower seat sealing faces for achieving primary sealing between disc and seat.
- Positive disc stem engagement by a precision machined square drive, eliminating potential leak path and failure of stem joint.
- High flow disc Butterfly Valve design provides a streamlined flow passage, enhanced flow characteristics and reduced resistance to flow especially for control applications.
Stainless Steel Series SS-1000 Butterfly Valves

- Valtorc Butterfly Valves stem sealing is accomplished utilizing the Seat as the primary seal.
- The Back-up ring (8) keeps the seal stationary should there be deflection or lateral movement of the stem.
- The captured Double O-Ring Seal isolates the Delrin Top Bushing.
- This triple seal / bushing Butterfly Valve system makes the stem isolation secure and reliable even in the most demanding applications.
- This Buttefly Valve is also furnished with an Anti-Static Pin Spring eliminating the possibility of static discharge due to the isolation of the stem / disc from the body

1st Offset
To have positive sealing and increase sealing capacity, the axis of the shaft is placed behind The center line of sealing point.
2nd Offset
To reduce running torque and friction between disc and Seat, the axis of the Butterfly Valves shaft is eccentric to the center of the valve and piping line.
3rd Offset
Cone shaped disc seat and body seat is inclined around the axis of the seat and center line to remove abrasion of the seats.
