Industrial RSBD 9BX4PFFNF Safety Relief Valve

The Industrial RSBD 9BX4PFFNF Safety Relief Valve is a Sarasin‑RSBD Starflow 9 Series spring‑loaded safety relief valve designed to protect process equipment from overpressure by venting when the set point is reached. Verified specifications indicate a set pressure of 3 bar and a maximum operating temperature of 147°C, enabling use in steam and select liquid services within that range. The valve is listed with MPN 11623001 and is noted to be manufactured in France, aligning with the Sarasin‑RSBD product family’s European origins. As a member of the Starflow 9 Series, this model belongs to a line of compact safety relief valves that rely on a spring mechanism to open at the specified pressure and restore once conditions return to normal. This configuration is intended to protect vessels and piping by discharging excess pressure to the atmosphere or a safe relief path once the pressure exceeds the 3 bar setting, helping prevent equipment damage and potential safety hazards in industrial plants.
