Double Flanged Butterfly Valves
A45
|
GENERAL INFORMATION Series A45 double flanged butterfly valve features a bonded liner extending over the flanges. The double flange design is suitable for high pressure loading and for use in heavy industry, shipbuilding, severe vacuum applications and water treatment industry like potable water, water treatment and wastewater applications. FEATURES • ISO5211 top flange together with stem heat suitable for direct mounting of actuators
• Stem anti-blowout design keep safety in field use
• Bonded seat protects the body and shaft out of contact with medium
• No exposed pins or bolts for stem-to-disc connection
• Single flange mounting is possible
• Can be installed in any desired position
• Bubble-tight shut off at full pressure rating
• Large flow capacity and enough strength
