BFL/BTL40~400
PRESSURE RELIEF VALVE
Description
The BFL pressure relief valve remains closed until the system pressure reaches the set maximum limit. At that point, it rapidly opens to release excess pressure. Once the pressure falls back to the set level, the valve closes gradually to avoid any pressure surges.
