OFFICINE RIGAMONTI SAFETY VALVE 1/2 3 ATE M / PM PRESSURE GAUGE CONNECTION PN10 115 ° C

"""The safety valve with manual opening with the """"LIGHT"""" handwheel, is an automatic valve designed to open in case of pressure
internal system, verifiable on the pressure gauge if installed, reaches the maximum preset limit (Nominal pressure of
Pnr calibration), allowing the water to let off steam through it. The safety valve automatically resets when the internal pressure of the system returns below the nominal calibration pressure. All the moving parts and the regulation spring of this safety valve are isolated from the heat transfer fluid by means of an industrial rubber membrane. The safety valve with handwheel opening """"LIGHT"""" meets the essential safety requirements laid down by the European Directive 97/23 CE PED (Pressure Equipment Directive).
