NOTES: 1)
2830 Mixing V
alves have two inlets
and one outlet. Published shut-off values are with respect to worst case conditions with zero downstream pressure on the outlet port and zero upstream pressure on the opposing inlet port. Pneumatic Actuators used with the 2930 are direct acting. The upper port fails closed on loss of air pressure to the actuator
.
2) 2830 Seat closure ANSI Class IV
.
3) Inlet
pressure
cannot
exceed Body
Pressure-T
emperature Rating.
4)
The 3-15 and 1-17 columns of the table apply to valves with control signals coming directly from I/P transducers with matching ranges. The 0-30 and 0-40 columns apply to valves with a positioner or an I/P transducer of suitable range.
5)
N/A indicates that the air signal is not capable of providing any shut- off or it exceeds the actuator’
s
maximum air pressure. Maximum air pressure DL49…30PSIG DL84 & 84XR…30PSIG
1)
Published shut-off values are for diverting applications. The values are worst case and based on the pressure difference between the inlet and the outlet that is closed. Consult the factor
y if the required
shut-off exceeds the published value and the pressure at the inlet and both outlets is known. For proper operation in diverting applications, the pressure difference between both outlets must not exceed 50 PSI. Consult the factor
y for shut-off values
for 2832 mixing applications. Pneumatic Actuators used with the 2832 are direct acting. The upper port fails closed on loss of air pressure to the actuator
.
2) 2832 Seat closure ANSI Class III. 3) Inlet
pressure
cannot
exceed Body
Pressure-T
emperature Rating.
