Safety valves

 

Safety valves are devices used for the protection of the systems and are usually used to control the pressure of the carrier systems for air, saturated steam, superheated water, nitrogen and gases. Upon reaching the set pressure, the valve opens by means of the "burst" of a shutter which offloads into the atmosphere or into a conducting pipe, thereby preventing the system's pressure from reaching critical levels ​​and safeguarding the system and all its parts.

The MBM model safety valves are direct spring types and comply with the 2014/68/EU Directive (PED Directive) classified under category IV. The certification was obtained with a very high discharge coefficient (K = 0.96) that allows a great discharge flow rate even with small models. The input port sizes range from 1/2" to 2" with the possibility of having both threaded or flanged connections. The atmospheric counter-pressure setting range varies between 0.5 and 15 bar (relative).

 

The valves are constructed in versions with or without lifting device (reset) and can be used for air, saturated steam, superheated water, nitrogen and gases falling within group 2 (2014/68/EU Directive). The MBM safety valves are constructed entirely in stainless steel both in the closed cover version and in the one with lifting device (reset).

Safety valves are typically installed in all systems where there is a steam generator, therefore, in the textile, food and industrial sectors. Every valve is tested at a pressure setting and subsequently equipped with a "Calibration Certificate". On request, the valves can also be certified INAIL.
