Abstract
The invention relates to a device for actuating double seat valves, which are especially suitable for the food and beverage industry and which have an independently actuated first closing element () and a second closing element () actuated dependently on it, whereby the actuation () always shows via a main adjustment device () for the full open position (H) as well as, for the case of maximum requirements, the respective individual adjustment devices () which are assigned to the closing elements () for generation of the partially open positions (T, T) for the seat cleaning of the closing elements (). The object of the invention is to design a device according to this generic type, that is constructed as simply as possible and that the first partially open position (T) of the independently actuated closing element () is adjustable from the outside of the device. This is achieved in that a stop position of the second actuating piston () relative to the housing () provided for the first partially open position (T) of the first closing element () of the individual adjustment device () and is adjustable from its exterior in the area between the main adjustment device () and the individual adjustment devices () through a stop nut ().
