Pressure Reducing Valve

Pressure Reducing Valve (PRV) is spring loaded diaphragm-actuated Valve. Normal set pressure of a Pressure Reducing Valve is 1- 3 Kgs/ sq.cms for an upstream pressure of 9-13 Kgs/Sq.cm. depending on ambient temperature.

The Pressure Reducing Valve provides superheat for the chlorine vapour thereby reducing the chance of re-liquification in pipeline downstream of Pressure Reducing Valve. If the Pressure Reducing Valve is by-passed the super heat provided by PRV will be lost. Besides, chlorine gas metered at the Flowmeter/ Rotameter will be more precise. If the flow of chlorine is metered at reduced constant pressure.

Use PRV in conjunction with Gas Filter to avoid impurities getting stuck in the seat of the PRV
