Control valves are pressure ves­
WARNING
sels designed and rated for spe
cific application conditions. Before installation, check the
serial number and / or the tag number to ensure that the
valve and actuator being installed are correct for the in­
tended application. Do not use the valve outside of its rated
design limits. Exceeding the design limits may cause haz­
ardous conditions including leakage of the process media
or rupture of the pressure boundary resulting in possible
process loss, equipment or environmental damage, or seri­
ous personal injury or death.
The specific product design data can be found on the valve's
serial plate, data sheet and the calculation sheet (in acc. to the
IEC 60534-7:2010).
The MaxFlo 4 handles a wide variety of appli cations, while
offering high flow capacity. Restricted trim and noise reduction
plates available as an option.
The MaxFlo 4 consists of the body, bonnet, trim, transfer case
and actuator. The valve is designed with a high level of
in terchangeability allowing the user to assemble the greatest
possible number of variations from a minimum number of
components to match each application.
The MaxFlo 4 is designed for use in ambient temperature range
-40°F to 158°F (-40°C to 70°C), air humidity up to 93% non-
condensing, air pollution up to 300 µg/m
by the accessories.
The product offering may include optional ancillary equip-
ment, such as positioners, air-filter regulators, solenoid
valves, limit switches or boosters. Digital, I/P , or pneumatic
positioners can be mounted directly, with a mounting bracket
or according to NAMUR standards. Refer to the relevant man-
ufacturer's user instructions for information regarding other
ancillary equipment.

3 Product Identification

Each MaxFlo 4 control valve comes with an attached serial
plate which includes key information specifically for each con-
trol valve:
The same serial number shown on the plate will appear on all
MaxFlo 4 data sheets, dimensional drawings, bills of material,
and spare parts lists. Other information located on the serial
plate is self-explanatory for the MaxFlo 4 control valve.
You can download .pdf versions of the MaxFlo 4 documenta-
tion including a sales brochure, technical bulletin and user
instructions at www.flowserve.com. It is the user's respon-
sibility to keep this and related documentation on file and ac-
cessible for the MaxFlo 4 product.
