Abstract (en)
[origin: EP0505866A1] The valve has at least two pistons 2, 7 which are under the action of at least one stored-energy device 10, 11 which attempts to hold the pistons against one another. Furthermore, the valve has at least two fluid-conducting connections A, B, of which the first connection A can be connected to a tank, the closing force of the valve increasing up to a predeterminable maximum value as the load pressure prevailing at the second connection B increases. Owing to the fact that means are provided which keep the maximum value of the closing force constant as the load pressure prevailing at the second connection B continues to increase, the valve can also be used for ranges of application having stringent safety requirements. <IMAGE>
