The 770075 RFI/EMI Shielded Nut Assembly is intended to provide RFI/EMI shielding on the inside of the housing.  Air which passes through the valve also passes through a 60 by 60 mesh Type 304 stainless steel cloth.  This cloth, when joined to the MIL-C-5541 Class 3 conversion coated aluminum body with silver-filled conductive epoxy, forms a faraday cage which protects the interior of the container from unwanted radio frequency and electromagnetic radiation.

The 770075 comes standard with a silicone base conductive gasket*, which is impregnated with Monel wire. In order to make the conductive path complete, the interior surface of the case, which the conductive gasket touches, must also be conductive.

Custom RFI/EMI Shielded Nut Assemblies are also available for: TA330 Pressure Relief Valves & TA333 Pressure Relief Valves and higher attenuation requirements using honeycombed aluminum or drilled holes.

*Conductive gasket utilizing other base materials are available upon request.
