Description

Flow is blocked from 1 to 2 until pressure increases to meet

the selected valve setting, lifting the poppet from its seat

and allowing relief ﬂow through port 2 to tank. Pressure at

port 2 is additive to the relief setting of the valve. The

cartridge is especially suited for pilot or thermal relief

applications.
