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 can be used in a diverting application but diverting valves can not be used in mixing applications.
d - SU- Stem Up; SD- Stem Down. Refer to Pg. 29, 2. VB-7000 Series ½"…2" Globe Valves for flow pattern, port designations and normal position.
