Model BV54 Rate of Flow Control Valve
Brand: Brodie InternationalThe Model BV54 Brodie Rate of Flow Control Valve is normally opened and designed to maintain a controlled flow rate within +/-2%.
The pilot is balanced, single seated valve with large ports and will operate on a differential as low as 5 psi (34.5 kPa).
The Model BV54 valve is pilot operated and operates on a balanced piston principle, spring biased to a closed position.
Pressure differential overcomes the force of the spring, causing the main valve to open and establish flow.
The Rate of Flow (Flow Limiting) Valve is normally open and throttles toward a closed position on increasing differential pressure.
