Wilkerson WBA208 Series United States

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 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.
