Fisher SS-263 Volume Booster
The SS-263 volume booster is used exclusively in Fisher Optimized Digital Valve (ODV) packages. It amplifies the output signal from the FIELDVUE™ digital valve controller to increase the stroking speed of pneumatic actuators. It can deliver high-volume output for fast stroking speeds when responding to large input signal changes or smooth, stable, low-volume output when responding to small input signal changes. This allows stable, accurate throttling control which is often necessary during the startup or commissioning of process control equipment.
Features
Fast Response: The SS-263 delivers high-volume output for fast stroking speeds when responding to large input signal changes and low-volume output when responding to small input changes.
High capacity: Flow capacities of roughly three times higher than the 2625 booster result in the need for fewer fittings, tubing, and units.
Noise Attenuation: Exhaust is passed through specially-designed passages to reduce the amountof ambient noise that is generated.
