Selection of safety valve specifications
Thread Content
What specification should the safety valve at the outlet of the DN250 water pump in the heat exchange unit be? What should be noted?
First, it’s necessary to know what the pressure is! And the temperature as well!! Is the medium water? Based on these values, the throat diameter of the safety valve can be determined, which in turn helps to determine its nominal diameter. For high-temperature applications, the A47Y type should be used!!! If the temperature is extremely high, radiators must also be installed. This is for your reference
First, the operating conditions of the equipment or system to be protected must be considered (such as operating pressure, allowable overpressure limits, properties of the medium, operating temperature, etc.), and secondly, the operating characteristics and parameter specifications of the safety valve itself

Reply to 4# MoMo: Without the necessary conditions, I have no idea what the diameter is!!! You haven’t specified the operating conditions!
