HVAC Service Butterfly Valves
HS(U)... Series Valves
Belimo resilient seat HS Series Butterfly Valves are designed for use in ANSI Class 150 piping systems and are supplied in standard lug style body designs. The comprehensive line of butterfly valves is available in sizes 2" to 30" and fullfills the requirement of commercial and industrial HVAC applications requiring positive shutoff for liquids.
• 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
