Introduction: Fisher/Fisher A31A low-temperature, high-performance butterfly valves are designed for extreme temperature, cryogenic applications, with an extended body that keeps encapsulated systems and actuators away from extreme temperatures. The valve also features a metal NOVEX eal seal that provides the stable durability required for tight shut-off, low operating torque, and cryogenic applications.
Features:
Developed as a valve/actuator package with a double D drive shaft, it can be easily mounted directly to gear and rack actuators without the need for an external coupling system.
The concentric rotation allows the butterfly to remain in the closed position even if the pressure increases suddenly or the actuator fails.
All components are interchangeable, including shafts and butterfly plates, simplifying servicing and reducing maintenance costs.
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 body can be automatically aligned on the bolts of the pipe flange, allowing for quick and accurate alignment of the valve to the pipe.
