WBA208 Series Precision Pneumatic Input Signal Amplifier

Brand: Wilkerson Corporation

Specifications
  • The WBA208 uses a pneumatic input signal to accurately control output pressure based on a predetermined ratio.
  • A balanced Supply Valve minimizes the effects of supply pressure variation.
  • An Aspirator Tube compensates downstream pressure droop under flowing conditions.
  • Optional Adjustable By-Pass Needle Valve allows tuning for optimum dynamic response (1:1 ratio only).
  • Optional Fixed Negative Bias allows operation with pneumatic devices that cannot be adjusted to zero input pressure.
  • A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
  • Unit construction allows servicing without removal.
  • Mounting Bracket available.
