    Abstract: The invention relates to a valve having a balancing function for a fluid distribution system. A valve closing member is movable between a closed position and a fully opened position. An actuation device is provided for changing the position of the valve closing member. A control unit is provided and comprises an electronic memory adapted to receive and store an opening limitation value, said opening limitation value being representative of a selected intermediate position between said closed position and said fully opened position of the valve closing member, wherein the control unit controls the actuation device to limit the movement of the valve closing member to positions from said closed position to said selected intermediate position. The invention also relates to a valve system and to a method of operating a valve.

    Abstract: The present invention pertains to a process for preparing a product rich in epichlorohydrin, comprising the steps of: a) reacting a mixture of dichlorohydrin and a base at a temperature in the range of 0-40° C. during a period of time in the range from 1 second to 180 minutes, wherein the base is present in a less than stoichiometric amount, to obtain a reaction mixture comprising epichlorohydrin and brine; b) subjecting at least part of the reaction mixture to a separation step to form a product fraction which is rich in epichlorohydrin and a brine fraction which is lean in epichlorohydrin; c) subjecting at least part of the brine fraction to a purification step to yield a purified brine. It has been found that the process according to the invention allows the manufacture of epichlorohydrin from dichlorohydrin on an industrial scale at high yield, while at the same time providing a brine with a low total organic carbon content without extensive separation being necessary.
