The SVA 100-200 stop valve has a limitation on the operating pressure differential, when the valve has to close/open. This differential closing pressure is according to EN12284 which is a part of EN378-1.
The table below states the maximum pressures at which the valves can be operated manually and tightness can be achieved.
