Audited Supplier Overview
YUMING Triple offset Bi-directional butterfly valve adopts the replaceable sealing structure of "Stainless steel and graphite laminated ". This ensures reliable sealing performance and a longer life span under frequent opening/closing working conditions.
• Multi-layer sealing
• Low opening torque
• Zero Leakage for both way
• Friction free between seat and sealing
• Fire safe design to API607
• Replaceable Seat & Disc Sealing
Applicable Standards
Valve Marking: MSS-SP-25
Design & Manufacture: API 609, EN 593
Face to Face Dimension: API 609, ISO 5752, EN 558
End Connection: ASME B16.5, ASME B16.47, EN 1092, JIS B2220, GOST 12820
Test and Inspection: API 598, EN 12266, ISO 5208, ANSI B16.104
Top Flange: ISO 5211
Structure
Triple offset butterfly valve add a third angular eccentric based on double eccentric structure. The third offset is consist of an certain angle be tween center line of valve body and conical seat sealing face, it ensure the sealing ring of the disc can be separated or touched with seat rapidly so that friction and squeeze between seat and sealing ring will be eliminated.
Bi-directional sealing design
This series could reach bi-directional Zero-leakage requirement in related standard, no mater the hydraulic test or the air test. The highest pressure ranting could reach is 600LB.
Low opening torque
This serial uses the Radial Dynamically Balanced Sealing System,by means of optimized design, the forces undertaken on both sides for the butterfly disc inlet and outlet become approximately balanced so as to effectively lower the valve opening torque.
Seal ring material
Seal ring of this serial is made of stainless steel plate with graphite/ carbon fiber/ PTFE etc. The main sealing is stainless steel plate, non-metal interlayer as the assistant one. This structure makes the valve more reliably sealed and the leakage of sealing reach VI class to ANSI B16.104 or A class to ISO 5208. Compare to the rubber asbestos plate material, our adopting material is more wearable, anti-flush, reliable and better for environmental.
Replaceable sealing ring
The sealing rings of disc and seat are all separate for YUMING series butterfly valve, and they could be replaced when needed. Either the seating ring of disc or seat could be changed individually when it's broken which not only lowers your maintenance cost but also makes maintenance easier.
Packing-combined sealing system
YUMING adopt this structure to ensure valve leakage could meet ≤20ppm at maximum. The dynamic sealing structure is available if necessary, which make the packing sealing under good condition and prolong the free maintenance period of packing.
Evenly Fixed Structure
Butterfly valve's sealing ring is fixed with evenly distributed bolts/nuts. Every bolt is precisely located and endure force evenly. This structure eliminates the problems of leakage or loose sealing ring due to uneven force of bolts and nuts.
Fire safe design and structure
Metal seated structure makes valve fire-safe and meet the requirement in API 607.
