Butterfly Valve Assemblies

Schneider Electric’s new butterfly valve line offers a wide range of two- and three-way sizes, along with low pressure pneumatic spring return, electric non-spring return, and spring return actuator models that operate with on/off, floating, or proportional control signals. All assemblies include industry leading butterfly valve features, stainless steel double “D” shafts, nylon 11 coated ductile iron disc machined to provide bubble tight shut off, minimum torque, and longer seat life. The tongue and groove resilient seat design with molded in O-ring eliminates the use of flange gaskets and allows for ease of maintenance or replacement of the resilient seat. These features provide years of optimum performance and reliability.

• 2 to 18” two-way assemblies and 2 to 16” three-way assemblies
• Chilled/hot water/glycol applications
• EPDM resilient seats with tongue and grove design and build in O-ring seal
• Stainless steel double D stem, requires no pins or screws to connect the disc and stem
• Extended neck design for temperature isolation and ease of insulation installation
• Nylon 11 coated ductile iron disc
• Wide choice of pneumatic and electric actuators and control signals
• Cast iron lug bodies mate with ANSI class 125/150 flanges
• Bubble tight shut off
• Bidirectional flow
