GENERAL INFORMATION

Series A23 wafer 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.

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
• Multi-standard alignment holes suitable for various standard of flanges of EN1092 PN10, PN16, ASME B16.5 CLASS150, JIS B2239 10K, 16K, BS 10 Table D, Table E
• Suitable for high pressure and full vacuum service due to the use of a cartridge seat design
• 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
