- Scope
- Low-pressure cut-off valves shut off the gas flow of the outlet pressure decreases below a preadjusted value, e.g. at a complete break down of the gas supply. Inlet and outlet of the low-pressure cut-off valve are connected by an overflow tube through which an automatic or manually actuated balance of pressure occurs. The flow rate throught this tube shall not exceed 30 or 100 dm<(hoch)3>/h respectively at an inlet pressure of 100 mbar. If, by this function, the outlet pressure exceeds the above mentioned preadjusted value, e.g. after reestablishment of the supply pressure, the low-pressure cut-off valve releases the gas flow automatically.#,,#
