The butterfly valve is an advanced quarter-turn rotational motion control valve capable of functioning as both a regulating valve and an on/off valve. Our company's long-life, energy-efficient butterfly valve employs a triple-eccentric principle design, optimizing the spatial motion trajectory of sealing surfaces to eliminate sliding friction between the disc and seat during the initial opening/closing phases (0°~10°). This innovation ensures:
1.Instantaneous separation of sealing surfaces upon opening
2.Immediate sealing contact upon closing
3.Extended service life and reduced wear

Design Features
1.Self-lubricating Bearing:The valve body adopts a thin-walled design, offering an aesthetically pleasing and lightweight profile with compact dimensions, reduced weight, and material efficiency, making it more economical compared to valves of the same nominal size.
2.Valve Body:The outer surfaceis precision-ground via centerless grinding, minimizing friction coefficient with the packing and significantly lowering valve actuation torque.
3.Valve Stem:A triple-eccentric design ensures mechanical sealingindependent of pressure differentials, maintaining reliable sealing even under low-pressure conditions.
4.Valve Disc:Equipped with a movable sealing mechanism and O-ring pre-tightening, the sealing seat tightly adheres to the disc, enabling automatic compensationfor long-term wear and extending service life. Sealing seats are customizable based on applications: metal seals, PTFE (polytetrafluoroethylene), or EPDM(ethylene propylene diene monomer) options.
5.Sealing Ring:Features a multi-layered sealing structure for enhanced durability. Depending on operational requirements, metal hard seals or RTFE (reinforced PTFE) seats can be selected.
