Abstract (en)
[origin: EP0659947A2] The invention relates to a control arrangement (10) for a shut-off valve which can be actuated by subatmospheric pressure and is intended for a subatmospheric-sewage system. The control arrangement comprises a main piston (22) via which valves (70, 72) can be actuated, in order to open and to close an extraction valve and an aeration valve independently of one another. <IMAGE>
