Description
FAIRCHILD Model 1500A Positive Bias Relay
Features
- Control sensitivity of 1" 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. - Unit construction lets you service the Model
1500A without removing it from the line.
