• Unique seat and disc design ensures positive valve sealing while maintaining low seating torque
• Butterfly valve discs are precision machined to half ball profile, providing a precise disc-to-seat relationship
• Cartridge style seat incorporates an elastomer bonded to a phenolic stabilizing ring, eliminating elastomer movement and reducing seat tearing or fatiguing due to bunching
• Cartridge seat has a much smaller mass of elastomer than traditional boot seat designs, limiting seat swell and the accompanying variations in seating torque
• The four bushing design completely isolates the valve shaft from the body, resulting in increased control of the valve disc, lower valve seating torque, and longer valve life
• No mechanical shaft-to-disc connections protruding into flow stream (2”-12”)
• Cast Iron Full Lug Bodies
• EPDM liner
• Stainless Steel Disc
• Two Models to suit the application: – HSU Series provides economical HVAC solutions up to 50 psi close-off with a 200 psi body rating – HS Series provides full-rated close-off to 200 psi (2”–12”) or 150 psi (14”–30”)
• 2-way and 3-way applications
