SB
Series Plastic Back Pressure / Relief Valves. 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 the valve 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. Inlet
pressure acts upward against the piston allowing excess pressure
to flow upwards through the orifice.
