Relief Valves

The Chemline SB Series Back Pressure Relief Valve stays closed until inlet pressure reaches the set pressure.

The spring tensioning bolt adjusts set pressure. This 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.
