Concentric Butterfly Valves
The Concentric DesignCCENTER OF SHAFT / 'Seat in the 'Center of Valve Body' Applicable for BUTTERFLY VALVE WITH ELASTOMER LINING.
Classification by Connection type
• Symmetric disc design ensures favorable flow characteristics and low pressure drop• Concentric shaft ensures low operating torque• Lining gives a good protection to valve body, and acts as flange gasket - Shaft penetrates the valve seat - Limited choice of seating materials(Elastomer, only)

TypeAppearance General Characteristics
AV-CWR(WAFER)
• General Applications - Shipbuilding, water works, heating and ventilation, power plants, oil refinery chemical plants etc.• Valve to be installed by long bolts between the flanges of adjacent pipe only • Easy handling and light weight.• Easy installation, less bolt quantity and low cost.• Inconvenient maintenance of adjacent pipe.
AV-CSR(SEMI-LUG)
• General Applications - Shipbuilding, water works, heating and ventilation, power plants, oil refinery chemical plants etc.• Similar as wafer type except a pair of the tap bolt hole in way of upper and lower sides for easy maintenance of adjacent pipe.• Easy handling and light weight.• Easy installation, less bolt quantity and low cost.• Keep liquid remained during repairing adjacent pipe.
AV-CLR(FULL-LUG)
• General Applications : general piping system pump outlets, tank drains, ship sides etc.• Ring shape bolt hole for bolting with flange of connecting pipe.• Keep pressure inside during repairing adjacent the other side pipe.• Different flange shape.• Possible damage on full face gasket.• Hard repairing of corroded bolt.• More man-hour for installation and body can be cracked by misaligned thread.• Heavy weight.
AV-CFR(FLANGE)
• General Applications - Shipside valves, ballast valves, water works, power plants, etc all piping system.• Both ends with complete flange.• Suitable to general pipe flange.• Suitable for shipside valve in the ship.• Heavy weight.• Same installation as ordinary valve.
Schema of concentric typeThe valve shall be a 90° turn clockwise to close, non-jamming, resilient seated valve for zero leakage service.The valve shall be torque seated and designed in such a manner that the disc can not be rotated freely at the closed position.Also this valve enables the fluid perfect shut-off regardless of the flow direction.
OperationsThe various operator of the valve is available depend on the valve location, driving medium and dedicated service of the valve to be provided.
• Manual lever operation• Manual worm gear operation• Pneumatic actuator operation• Hydraulic actuator operation• Electric motor actuator operation

Method for Carrying & Keeping Ace Valve Certificates
How to Install Butterfly Valve
Aligning of Flange Gaskets
Centering & Flanging of Valve
Bolts spanned, disc edge with inbody face-to-face.No disc edge damage,propersealing allowed
• Be careful not to get a scratch on Disc edge and Seat ring. The openings must be protected by plywood or other things when carrying valve.• Valve must not be shocked and shaken too much. It may cause the crack of neck, lever, handle and body• Valve must be protected from sunlight.• Valve to be kept and transported under partially opened.• The suitable temperature from -10℃ to 70℃ and humidity between 10% ~ 60% to be maintained.• During valve storage, check the smooth operation once per month.
Aligning of Flange bolts
Piping misaligned:Result-DiscO.D. touches pipe I.D. causing disc edge damage. Increased torque & leakage.Seat face, seals improperly withoutengagement
Piping aligned properly when bolts tightened, disc in full open position:Result-disc clears adjacent pipeI.D., seat face seals properly, noexcessive initial torque.
