Pressure Reducing Valve
Use of steam at correct pressure is important to achieve optimum heat transfer in process. Usually steam is used at available pressure without much thought on the choice. However, it is important to note that latent heat in steam is high at lower pressure. It means that less steam will be required for given process heat transfer if it is used at low pressure. As achieving desired process temperature in given time is the only criteria from process point of view, this temp. becomes the dictating parameter. Steam should be used at lowest possible pressure for a given process temp. Another well known fact about steam is the volumetric increase with reduction in pressure. For this reason, it is desirable to distribute steam at higher pressure from generating source to usage point. The logical approach to meet both the above needs is to reduce steam pressure very close to the point of usage.
it is therefore logical to use more PRV stations in a process plant. A PRV station comprises of PRV and accessories required with it to make the system reliable and uninterrupted.
