Pressure Reducing

Model BV50

The Model BV50 Brodie Control Valve is a pressure reducing valve designed to regulate a downstream pressure regardless of fluctuations in flow rate or downstream pressure. When correctly installed and adjusted, the Model BV50 valve will regulate downstream pressure at a value within +/-2 PSI (13.8 kPa) of the valve pilot’s setting.

Principle of Operation
The Model BV50 valve is controlled by a pressure reducing pilot which senses line pressure at a selected point and throttles the valve to maintain a desired pressure at that point. If line pressure at the sense point exceeds the setting of the pilot, the pilot throttles the valve until the correct pressure level is reached. Conversely, if line pressure at the sense point falls below the setting of the pilot, the pilot throttles the valve again until the correct pressure level is reached.
