Buyers and engineers often ask the same question: "Which butterfly valve is best for my system?" The answer depends on four key aspects: functional performance, valve structure, connection type, and operation method.
Here's a clear breakdown to help you choose the right butterfly valve for your project.
Water Butterfly Valve – For municipal water and wastewater treatment.
Tips: Commonly ductile iron body, EPDM seat
Ventilation Butterfly Valve – Large-diameter, lightweight, used in HVAC and flue gas pipelines.
Tips: Carbon steel or stainless steel body, soft seat
High-Performance Butterfly Valve – For higher pressure/temperature service.
Tips: Stainless steel body, PTFE or metal seat
Corrosion-Resistant Butterfly Valve – Handles chemicals and seawater.
Tips: Stainless steel, UPVC/CPVC/PVDF body, PTFE seat
High-Temperature Butterfly Valve – For steam and hot gases.
Tips: Carbon steel or stainless steel body, metal seat
Sanitary Butterfly Valve – Hygienic polished body for food, beverage, and pharma.
Tips: Sanitary 304L/316L body, EPDM/PTFE/silicone seat
Vacuum Butterfly Valve – Tight sealing for vacuum pipelines in scientific and semiconductor applications.
Tips: Tips: Stainless steel body, special sealing rings
Concentric (Resilient-Seated) – Rubber-lined, bubble-tight shutoff.
Tips: Cast iron/ductile iron or stainless steel body, EPDM/NBR seat
Double Eccentric – Offset disc reduces friction, longer seat life.
Tips: Carbon steel or stainless steel body, PTFE seat
Triple Eccentric (Metal-Seated) – Metal-to-metal sealing for extreme conditions.
Tips: Stainless steel body, hard alloy or stainless steel seat
Wafer Butterfly Valve – Compact, economical, clamped between flanges.
Tips: Common in ductile iron or stainless steel bodies
Lug Butterfly Valve – Threaded lugs allow one-side disassembly for maintenance.
Tips: Ductile iron or stainless steel body, soft or PTFE seat
Flanged Butterfly Valve – Strong connection, suitable for large-diameter or high-pressure pipelines.
Tips: Carbon steel or stainless steel body, various seats
Manual Butterfly Valve – Lever or gearbox operated; simple and cost-effective.
Tips: Available in all common body/seat materials
Electric Butterfly Valve – Driven by an electric actuator (12V/24V/220V), ideal for remote control and automation.
Tips: Typically stainless steel or cast body, PTFE/EPDM seat
Pneumatic Butterfly Valve – Powered by a pneumatic actuator, offering fast response and high torque.
Tips: Often stainless steel body, PTFE or soft seat; compatible with limit switches and positioners
