Introduction: The Fisher/Fisher A11 High Performance Butterfly Valve is a reliable, high-performance butterfly valve for throttling and switching applications. The valve is available in a bi-clamp or single-flange design to maintain tight shut-off for long periods of time and is specific for a wide range of pressure and temperature conditions, including cryogenic applications.
Features:
Choice of square, keyway or splined shaft connections.
The pressure-assisted seal design provides tight cut-off.
Trim and bolt materials are available for acidic liquid and gas applications.
The installation of the sealing ring screws does not interfere with the sealing function of the flat or wound gaskets of the pipe flange.
The valve design features the same torque required to open and close the valve regardless of the direction in which the pressure is applied.
All components are interchangeable, including shafts and butterfly plates, simplifying servicing and reducing maintenance costs.

Fisher/Fisher pipe silencer
Complete Fisher pipe silencers provide superior noise reduction performance for applications where valves generate a lot of noise. Once installed, the total system pressure drop is split between the valve and the silencer. This allows the valve to operate at a lower pressure drop ratio, reducing the noise generated during the flow through the control valve.
