P/T Ports
Installation
For 1/2 and 1-1/4-inch
Normally Open
Valves
The low-pressure P/T port (blue indicator ring) should be located on the downstream side
of the valve. The high-pressure P/T port (red indicator ring) will be located on the upstream
or inlet side of the valve.
NOTE:
1-1/2- and 2-inch Normally Open valves ship with P/T ports installed.
For 1/2 to 1-1/4-inch
Normally Closed
Valves
The low-pressure P/T port (blue indicator ring) should be located on the side of the valve
with the raised lettering and label. The high-pressure P/T port (red indicator ring) will be
located on the opposite side.
Presetting
Adjustment
Prior to mounting the actuator, verify the valve is set to ordered flow setting (suffix of part
number).
