Type 2502F Controller with Reset Relief
Valve
This construction (figure 13) has a differential relief
valve used to prevent proportional pressure from ex-
ceeding reset pressure by more than a set value, a
feature useful for intermittent control applications. Pro-
portional valve output registers in the outer chamber of
the relief valve as well as in the proportional bellows.
