The Truflo BRP Series Back Pressure/Relief Valve serves a dual function. When installed downstream of a pump, it operates as a back pressure valve, maintaining constant pressure beneath the metering pump.

When placed in a tee fitting, it functions as a relief valve, opening once the inlet pressure exceeds a preset level. The pressure activates the piston, allowing liquid under higher pressure to flow through the orifice, ensuring safe and controlled operation.
