Is it necessary to have a PRV valve on the low pressure side?

Answer:The pressure relief valve (PVR) shown in the photo of the Victor Compressed Air Regulator - SR 450D - Heavy Duty show the PVR mounted on the same side of the regulator as the low side connection . Although it is mounted in this position it is main PVR for the entire regulator not just for the low side. it will not provide protection for the low side only
