AVFI’s AB Series Butterfly Valve with hard phenolic seat, pin or splined connection between disc and stem, both wafer and lug style. Suitable for most general purpose applications.
TOP FLANGE
Top flange as per ISO 5211 standard for simple fitting of handle or actuator.
DOUBLE O-RING
Prevents leakage from stem.
BUSHING
Stem bushing reduces valve torque and prevents stem corrosion. PTFE or bronze available.
SEAT (LINER) Phenollic backed, non-collapsible with good stretch resistance, easily replaceable.
STEM CONFIGURATION
Square on sizes up to 300mm and round on sizes 350mm.
SHAFT SEAL
Bonding of elastomer to phenolic backing ring protects against distortion. A common cause of shaft leakage.
CONNECTION BETWEEN DISC & SHAFT
Pin, spline or square connection are all available.
DISC
Precision profile disc provides bubble-tight shut-off and assures minimum torque value and long seal life.

Note: All torque value in left chart were derived from the actual test data using water at 20°C. For torque used in other media, please contact AVFI directly. Torques shown do not include safety factor.
For actuator selection, AVFI recommends:For EPDM, NBR, VITON and HYPOLEN seat, these valves be multiplied by 1.35 to 1.5 for single valve applications.For PTFE seat, multiply the above numbers by 2.
Kindly note under certain conditions, hydrodynamic torque can meet or exceed seating and unseating torques.
