WBA45 Series Precision Pneumatic Input Signal Amplifier
Brand: Wilkerson Corporation
Features
- 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
