Specifications
  • Five signal to output ratios meet most control element requirements
  • Control sensitivity of water column allows use in precision applications
  • Large Supply and Exhaust Valves provide high forward and exhaust flows
  • Soft Supply and Exhaust Valve seats minimize air consumption
  • A balanced Supply Valve minimizes the effect of supply pressure variation
  • An Aspirator Tube compensates downstream pressure droop under flow conditions
  • A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
  • Optional remote feedback port minimizes pressure drop at final control element under flow conditions
  • The optional adjustable By-pass Valve lets you tune for optimum dynamic response (1:1 ratio only)
  • Unit construction lets you service the WBA45 without removing it from the line
