Across the varied applications we service, it is necessary to have a high-quality and reliable relief valve for your system. MRC Global has the products and expertise to meet this need. Our relief valve inventory is all certified to industry standards and are configured in accordance to safety and capacity requirements for even the most demanding processes.

Our comprehensive product range of safety equipment helps customers reliably protect systems for generating, storing, and transporting gases and liquids of every hazard category against dangers such as endurance burning, deflagration and detonation. Our complete line of valves enables tank farms to be safely and economically ventilated.

During free venting or blowing off of pressurized steam or gas kinetical energy in terms of waves with high pressure amplitudes is released. This effect causes already at an minor amounts of venting media and relatively low expansion pressures a quite high sound pressure level. At bigger blow off flow and higher expansion, e.g. blowing of safety valves, the sound pressure level SPL can increase up to 150 dB(A). This radiation of noise can be reduced effectively with blow off silencers, preferably with expansion stages (orifice).

MRC Global offers a full range of silencer solutions and noise reduction devices for safety valves and control valves.
