Latsha - Pressure Reducing Valve

Pressure Reducing Valve (PRV) is a spring-loaded diaphragm-actuated valve. The normal set pressure of a PRV is 1-2 kgs/cm2 for an upstream Pressure of 9-13 kgs/cm2 depending on the ambient temperature. The PRV provides superheat for the chlorine vapor thereby reducing the chance of reliquification in the pipeline downstream of PRV. If the PRV is by-passed the superheat provided by well be lost. Besides, chlorine gas metered at the flowmeter/rotameter will be more precise. If the flow of chlorine is metered at reduced pressure. Use PRV  in conjunction with a gas filter to avoid impurities getting stuck in the seat of the PRV
