ACTUATOR CLOSE-OFF PRESSURE RATING (psi)
a
b
a
Close-off ratings for mixing valves: (SU = “A”, SD = “B” port). “A” port (SU) ratings equal pressure at port “A” minus pressure at port “B”. “B” port (SD) ratings
equal pressure at port “B” minus pressure at port “A”. Close-off ratings in the table are true only when the indicated supply air pressure is applied to the actuator.
A change in air pressure at the actuator alters the actual close-off pressure.
b
Close-off pressure ratings describe only the differential pressure which the actuator can close-off with adequate seating force. Consult valve body spec-
ifications for other limitations.
