2 Intended Use

Diaphragm linear actuators are
WARNING
pressure vessels designed and
rated for specific application conditions. Before installa-
tion, check the serial number and / or the tag number to en-
sure that the valve and actuator being installed are correct
for the intended application. Do not use the valve assem-
bly outside of its rated design limits. Exceeding the design
limits may cause hazardous conditions including leakage
of the process media or rupture of the pressure boundary
resulting in possible process loss, equipment or environ-
mental damage, or serious personal injury or death.
Specific product design data can be found on the actuators
serial plate, data sheet and the calculation sheet (in acc. to the
IEC 60534-7:2010).
The FlowAct handles a wide variety of general service ap-
plications.
The FlowAct consists of the actuator, yoke and attachments
and accessories. The actuator is designed with a high level
of interchangeability allowing the user to assemble the great-
est possible number of variations from a minimum number of
FlowAct Diaphragm Linear Actuator
components to match each application. There are two fail safe
positions, close or open without or with attachments.
The FlowAct is designed in compliance with EN 1349:2009
- Industrial Process Control Valves (DIN EN 1349 and VDE
0409-1349).
The FlowAct actuator is designed for use in MODERATE and
WORLDWIDE environmental conditions, standard ambient tem-
perature range -40°C to +80°C (-40°F to 176°F). A special ver-
Stroke (mm)
sion is available with conditions up toup to -60°C, air humidity
10 - 20
up to 93% non-condensing, air pollution up to 300 µg/m
20 - 40
less restricted by the accessories).
20 - 60
20 - 100
The product offering may include optional ancillary equipment,
40 - 100
such as positioners, air-filter regulators, solenoid valves, limit
switches or boosters. Digital, I/P, or pneumatic positioners
can be mounted direct or with a mounting bracket. Refer to
the relevant manufacturer's user instructions for information
regarding other ancillary equipment.

3 Product Identification

Each FlowAct diaphragm linear actuator comes with an at-
tached serial plate which includes key information specifically
for each actuator:
The same serial number shown on the plate will appear on all
FlowAct data sheets, dimensional drawings, bills of material,
and spare parts lists. Other information located on the serial
plate is self-explanatory for the FlowAct actuator.
You can download .pdf versions of the FlowAct 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 FlowAct product.
4 FlowAct Modification
FlowAct linear actuators are generally delivered as tested and
assembled units.
