A flat gate valve is a sliding valve in which the closing members are parallel rams. The closing member may be a single shutter or a double shutter with a distracting mechanism therebetween. The pressing force of the shutter to the valve seat is controlled by the medium pressure acting on the floating shutter or the floating valve seat. In the case of a double gate flat gate valve, the expansion mechanism between the two shutters can supplement this pressing force.
