A24 Lug Concentric Butterfly Valves, Cartridge Type Seat Butterfly Valves, Streamlined Disc and Strong Stem-to-Disc Connection Butterfly Valves-ABC-valve

GENERAL INFORMATION TECHNICAL DATA PARTS LIST AND MATERIAL SPECIFICATION DIMENSIONS(mm)

GENERAL INFORMATION

Series A24 lug concentric butterfly valve features a cartridge type seat, streamlined disc and strong stem-to-disc connection for easy use in many industrial applications such as food and beverage, pulp and paper, chemical, mining, water treatment, power plants, etc. Full rated unidirectional dead-end service is achieved by a lip designed in the lug body.

FEATURES

• ISO5211 top flange together with stem square suitable for direct mounting of actuators
• Stem anti-blowout design keep safety in field use
• Dirtscraper prevents moisture penetrating into the shaft area
• Suitable for high pressure and full vacuum service due to the use of a cartridge seat design
• Full rated unidirectional dead-end service is achieved by a lip designed in the lug body
• No exposed pins or bolts for stem-to-disc connection
• No need for flange gaskets
• No risk of damage to the valve during installation in closed position
• Bubble-tight shut of at full pressure rating
• Large flow capacity and enough strength because of streamline disc design
• Plug with O-ring sealing eliminates any leakage from the stem
