-
When the valve is closed in the position of rest, the diaphragm under the valve seat is only impinged by the low secondary pressure. Any rise in working or primary pressure lifts the diaphragm against the spring force. The valve opens and the pressure decreases
-
Can be adjusted easily across the entire pressure range
-
Can be secured against unauthorized opening by sealing
-
The pressure relief valve, which is directly controlled by the medium, is used in technical processing plants for keeping pre-set working pressures constant on the primary side
-
The pressure relief valve can also be used as an overflow valve to prevent pressure peaks. In this case, the pressure relief valve is fitted in a bypass line
-
Pressure relief valves are not safety valves in the sense of the pressure vessel directive
