Plastic, Back Pressure Valve, Pressure Relief Valve SB17 Series from Chemline


The Chemline SB Series Back Pressure/Relief Valve has two functions. As a Back Pressure Valve, installed in-line downstream of a pump, the back pressure below the metering pump is maintained. When installed in the branch of a tee it is a Pressure Relief Valve. The valve stays closed until inlet pressure reaches the set pressure which is adjusted by turning the spring tensioning bolt. The “Mini” SB17 size relief valves offer high performance in a compact package.
