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”
• Body materials: PVC, PP, PVDF
• Ends: True union socket, threaded or ChemFlare
• Seals: EPDM or FKM
