Abstract (en)
[origin: EP0900963A1] The seat valve (S) has a closure member (3) with an adjusting drive (5,7), and a device to load the member in the closing position on the seat. The device consists of a mechanical, non-positive locking unit (R), released by the valve drive, with the sealing position locking force acting in the closing direction of the member. The bistable locked seat valve has adjusting impulse transmitters, to release the locking unit. The unit acts as an auxiliary adjusting drive, beginning at its release point. The adjusting drive has at least one switching magnet (M1,M2) for each direction. The valve is a 3/2-way path valve.
