BFL/BTL Pilot-operated 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.
Features
• Ductless design with a compact size for easy transportation, installation, maintenance, and repair.
• Releases pressure when pipeline pressure exceeds the set limit.
• Relief valve is suitable for general liquids and gases.
• Suitable for both horizontal and vertical installation.
• Wide capacity range, capable of handling local water supply pressure and adapting to specific pump specifications.
• The pressure regulator allows for easy pressure adjustment.
• Easy to maintain, with maintenance parts available upon request.

BFL/BTL Pilot-operated Pressure Relief Valve
The BTL/BFL pilot-operated relief valve quickly releases excess pressure when it exceeds the set value and gradually closes once pressure stabilizes, ensuring a steady water supply.
