Abstract
A valve block, in particular for aggressive fluids and/or fluids of increased temperature, includes a plurality of valve cartridges and an adapter for attachment of the plurality of valve cartridges. The adapter includes passageways for communication with each individual valve cartridge. The adapter is made of plastic material through an injection molding process and includes fittings for attachment of hoses, with the fittings being injection molded and fixed to the adapter through ultrasonic welding. At a location before and behind each valve cartridge are metallic electrodes fitted in the adapter and electrically connected to an analyzer so as to form an electric circuit which is closed by the electrically conductive fluid in order to allow each valve cartridge to be monitored for leaks.
