Fluid Pressure Relief Valve

Some systems may require installation of a
pressure relief valve at the pump outlet to pre-
vent overpressurization and rupture of the
pump or hose.
Thermal expansion of fluid in the outlet line
can cause overpressurization. Thermal
expansion can occur when using long fluid
lines exposed to sunlight or ambient heat, or
when pumping from a cool to a warm area (for
example, from an underground tank).

Overpressurization also can occur if the pump
is used to feed fluid to a piston pump, and the
intake valve of the piston pump does not
close, causing fluid to back up in the outlet
line.
