ABSTRACT:
A valve suitable for connection to a vacuum sewer system and comprising a flow duct with a resilient wall which acts as a flow duct closing member. Outside the wall with respect to the flow duct there is a closed chamber connectable to suitable pressure sources in order to move the resilient wall by means of pressure between a flow duct closing and a flow duct opening position. In order to improve the closing movement of the valve the resilient wall is provided with a stiffener at the outlet side of the flow duct.
