FRLF Pressure Relief Valve for Fire Fighting
Description
• The pressure gauge displays the inlet pressure on the primary side.
• The valve body is made of stainless steel and cast with a piston structure that can withstand high pressure.
• Installed in the pump room, it is suitable for fire connection system pipelines.
• A shut-off valve is required on the pipeline before the relief valve for ease of future maintenance.
• Ensure thorough removal of foreign objects and install a filter to prevent blockages.
• It can be installed horizontally or vertically, with the air cock on the valve body kept open at all times.
• In cases of insufficient flow, avoid installing upside down (with the inlet facing upward).
• For special acidic, alkaline, or oily fluids, custom manufacturing is required.
Features
• A relief valve is a safety device designed to release excess pressure and prevent accidental system damage.
• The direct-acting relief valve is suitable for general liquids and gases.
• Applicable for automated control systems and various general fluid applications.
• Wide capacity range, capable of handling local water supply pressure and adapting to specific pump specifications.
