ACTUATOR CLOSE-OFF PRESSURE RATING
a b c
a
Close-off ratings for mixing or sequencing 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
specifications for other limitations.
c
Mixing valves are not to be used in diverting applications. Diverting valves may be used in mixing applications with minor affects on flow.
