Back
Pressure Valves Pressure Relief Valve
SB Series 10 & 11
The
Chemline SB Series Back Pressure/Relief Valve has two functions.
As a 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 on the Teflon® control diaphragm opening
the valve, allowing excess pressure to flow downwards through
the orifice.
The
SB10/11 Series is very sensitive to pressure changes and requires
low overpressure to fully open.
