Main Technical Parameters
Precise specifications, proven performance under severe working conditions.
Product Features
Original design, long-term sealing and precise regulation.
- The seat is bidirectionally reversible to extend valve service life.
- The triple-offset principle minimizes friction between the disc and seat.
- No non-metallic elastic elements are used at the joint between valve body and seat, eliminating seal failure caused by long-term ageing of elastic components.
- The all-metal floating resilient seat enables automatic alignment of the disc against the seat. Thanks to the resilient structure of the seat, automatic compensation for wear on the sealing face of the seat is achieved.
- Oil-free bearing technology is adopted for upper and lower stems to enhance self-lubrication and reduce stem friction resistance.
- Dual safety structure. To prevent sudden accidents resulting from stem breakage and ejection for various reasons, a pin connection is fitted between stem and disc, together with a unique composite resilient retainer for anti-ejection protection.
- High-performance packing design. Besides preventing stem ejection, the resilient retainer also provides elastic compensation for packing. This detailed design to avoid external leakage allows the butterfly valve to be applied in pipelines carrying toxic and hazardous media for petroleum, chemical and other industries.
- The two-piece stem design creates a larger flow passage at the centre of the disc, improving the flow capacity of the valve.
