ACTUATOR CLOSE-OFF PRESSURE RATING (psi)
abce
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 to standards with adequate seating force. Consult valve body specifications for
other limitations.
c
Mixing valve are not to be used in diverting applications. Diverting valves may be used in mixing applications with minor affects on flow.
