Double Regulating Valve ( DRV )
A double regulating valve "also known as a balancing valve" controls the water flow across chilled water air conditioning equipment.
It is installed to the return line of the equipment, and the flow is controlled and balanced to the design flow by adjusting the valve spindle.
Earlier, the pressure drop across the coil is measured, and the valve spindle is adjusted accordingly to achieve the required flow.
The advancement in the double regulating valve is pressure independent control valve " PICV ", which shall ensure the exact flow as marked in the valve in each spindle turn.
