Pressure
Relief Valve Back Pressure Valves
SB Series 12
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. Inlet
pressure acts upward against the piston allowing excess pressure
to flow upwards through the orifice.
The
SB12’s have a built-in check valve function, desirable for dosing
applications. They are not so sensitive as to open with every
pulsation from a metering pump.
