The Model A106-DL-Air is a compact sewage relief valve that is suitable for 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 an otherwise difficult application due to high pressures or space limitations. The Model A106-DL-Air-ET retains all the features and benefits of the Model A106-DL-Air and also features two three-way solenoid valves that force the valve open upon power failure.
