  • Patent number: 11035478
    Abstract: Provided is a gate valve for industrial plants, in particular for chemical and petrochemical plants. This gate valve comprises a slide rod, which is movable in the axial direction, at least one slide plate for closing the gate valve and at least one pressing member. The pressing member is connected to the slide rod and presses the slide plate against a sealing seat. Furthermore, the gate valve comprises a spring element for acting on the pressing member with a release force and a fixing element which is arranged on the slide rod for transmitting power between slide rod and spring element. The gate valve according to the invention comprises a fixing disc as a fixing element, which surrounds the slide rod and is positively connected to the slide rod.

  • Patent number: 9784373
    Abstract: The invention relates to a shut-off device for valve systems of industrial plants, in particular of chemical and petrochemical plants, with a disc (12) to shut off an opening for a fluid flow and with a seal seat (13a). The invention is characterised in that the disc (12) is arranged between the seal seat and a pressing means (26) to subject the disc (12) to a pressing force and can be pressed by the pressing means (26) against the seal seat (13a), wherein the pressing means (26) has in a housing (10) a plurality of pistons (48) and a transmission element for transmitting the pressing force to the disc (12), the transmission element being arranged between the pistons (48) and the disc (12) and extending along the disc circumference, and wherein the pistons (48) are fluidically connected by a feed line (49) for hydraulic fluid.
