Zero Leakage Wafer Gearbox Operated Butterfly Valve 12& acute;& acute; For Petrochemical Processing
?
?
Description:
1 . Mounting Flange: ISO5211 mounting flange accommodates direct mouting of all types of actuatores, including handles, gear operators, electric and pneumatic.
2 . Stem Configuration: The connecting key holds a high accuracy and a heavy strength suitable for both operation handle installation and actuators.
3 . Bushing: Stem bushing reduces torque and isolates the stem from the valve body, preventing seizure of the stem due to corrosion in the stem journal.
4 . One-Piece Thru Shaft: Ensures dependability and positive disc positioning.
5 . Smooth Finished Disc : The valve disc of a high precision polishing treated, highly precisely matched with the seat ring, of a good tighness, no leakage at the shaft. ?Provides bubble-tight shut-off and assures minimum torque and longer seat life
6 . Precision Taper Pin: Ensure positve, vibration proof, shaft to disc connction. Field replaceable.
7 . ?Seat: Phenolic-back seat is non-collapsible, stretch resistant, blow out proof, and field replaceable.
