The Model A106-DL-Air is a compact sewage relief valve that is suitable for high pressures up to 200 psi, responds very quickly and retains all the features and benefits of the Model A106-DL Spring– Hydraulic version.

It is an attractive solution to what may be otherwise a difficult application due to higher pressures or space height limitations.

The Model A106-DL-Air-ET retains all the features and benefits of the Model A106-DL-Air with the additional feature of two 3-way solenoid valves which forces the valve open upon power failure.
