Valve with a device against water hammer |
摘要 |
The valve has a piston-shaped valve control element (5) which is moved in an axial direction between a closed position and an opened position, in order to lock or to open the flow between the two channels. The valve control element has an inner passage which connects both the channels by the closed valve control element, if the pressure in the inlet channel (1) exceeds a defined value. |
