Fisher SS-263 Volymbooster

Fisher SS-263 Volymbooster

Fisher™ SS-263 volymbooster används endast i paket med Fisher Optimized Digital Valve (ODV). Den förstärker utsignalen från FIELDVUE™ lägesregulator för att öka sträckhastigheten hos pneumatiska ställdon. Den kan leverera högvolymutgång för snabba hastigheter vid svar på stora ingångssignaländringar eller jämn, stabil, låg volymutgång vid svar på små inmatningssignaländringar. Detta möjliggör stabil, exakt gasreglering som ofta är nödvändig vid start eller igångkörning av processkontrollutrustning.

  • 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.
  • Adjustable Response: The integral bypass restriction allows the booster to be easily and readily tuned to operate under small or large input signal changes.
  • Auxiliary Supply Connections: Supply air is readily available through two 1/4 NPT connections that are built into both sides of the unit for use with a Fisher 377 trip valve or other accessory.
  • 3 in 1 Connection: This special connection can provide any of the following connections, if needed: 1/4 NPT diagnostic connection for easy testing, 1/4 NPT actuator bypass assembly connection foruse on an actuator with a handwheel, and 3/4 NPT connection
  • Soft-Seated Construction: Soft seated exhaust and supply valves provide for bubble tight shutoff toreduce unnecessary air consumption and ensure fail mode upon loss of plant air.
  • Robust Mounting: Flanged-style actuator mounting provides ease of maintenance, simplifiedtubing, compactness, and high vibration resistance.
