Manufacturer: Fisher — POSI-SEAL
Part number: A11
Category: Valves
High-performance butterfly valve for throttling and on/off applications. Concentric rotation design. NPS 3 through 24.
Description
The Fisher A11 is a reliable, high-performance butterfly valve for both throttling and on/off applications. Concentric rotation ensures that the valve disk remains in the closed position even in the event of line pressure surges or actuator failure. Torque necessary to open and close the valve is the same regardless of the direction in which the differential pressure is applied. Interchangeability of all parts including shafts and disks simplifies service and reduces maintenance costs. Seal retainer screws are located so there is no interference with the sealing function. The valve body self-centers on the line flange bolts for fast, accurate centering in the pipeline.
