When installed in-line downstream of a pump, Chemline’s SB12 Series Back Pressure/Relief Valve functions as a back pressure valve. When installed in the branch of a tee it acts as a pressure relief valve.

SB12 Series also has a built-in check valve function that prevents reverse flow. It does not open with every pulsation from a metering pump. It is designed for clean fluids only.

Available in:

  • Sizes: 3/8” to 4”
