The Model K80A Differenlial PressureValveisa hydraulically operated pilot-controlled. modulating valve. It is designed to maintain a constant pressure differenlial between any two pressure points ina System where the closing of the valve directly causes the differenlial pressure to increase. The valve tends to open on an increase in different pressure and dose on a decrease in different pressure. Especially used in air condition System. In operation, the valve i$ actuated by line pressure through a pilot controi System sensing form two points across which a differenlial is to be maintained Operation is completely automatic and pressure settings ma y be easily changed.
