Pressure reducing valve is a device which reduces and stabilizes the upstream pressure to an adjusted downstream pressure. When the entering pressure from the public mains is too high and variable, pressure reducing valve stabilizes the downstream pressure to the adjusted one. Possible variations of the upstream pressure do not influence the adjusted downstream pressure. This range of pressure reducing valves allows the operator to adjust the downstream pressure to a set figure.

Installation
BDV 25 must be installed on a horizontal pipeline with the fl ow direction as indicated by the arrow on the product body.

How to use the chart? The curves numbered 2,3,4,5,etc. Represent up-stream pressures. Downstream pressures are read along the vertical line on the left hand side of the chart.
