The Model BV60 Brodie Control Valves are back pressure regulators designed to maintain a specific minimum upstream pressure regardless of fluctuations in flow rate or downstream pressure. When correctly installed and adjusted, the Model BV60 valve will maintain up stream pressure at a value within +/-2 PSI (13.8 kPa) of the valve pilot’s setting. A minimum pressure differential across the valve of 15 PSI (103 kPa ) is required for it to fully open.
