1.9 Valve and actuator variations
These instructions cannot claim to cover all details of all possible product variations, nor in particular can they prov-
ide inform ation for every possible example of installation, operation or maintenance. This means that the
instructions normally include only the directions to be followed by qualified personal where the product is being used
for is defined purpose. If there are any uncertainties in this respect particularly in the event of missing product-related
information, clarification must be obtained via the appropriate FLOWSERVE sales office.
2. Unpacking
Each delivery includes a packing slip. When unpacking, check all delivered valves and accessories using this
packing slip. Report transport damage to the carrier immediately.
In case of discrepancies, contact your nearest
FLOWSERVE location.

4. APEX A9000 Overview
The Apex A9000 is a two-wire loop powered, 4-20 mA input digital valve positioner.
The Apex A9000 positioner controls actuators with rotar y mountings.
The Apex A9000 is completely powered by the 4-20 mA input signal. The minimum input signal required to function is
3,6 mA. As an option the D20 can be equipped with HART protocol to allow bidirectional communication.
Since the positioner is insensitive to supply pressure changes and can handle supply pressures from 1,5 to 6 barg (22 to
105 psig), a supply regulator is usually not required; however, in applications where the supply pressure is higher than the
maximum actuator pressure rating a supply regulator is required to lower the pressure to the actuator
’s maximum ra- ting
(not to be confused with operating range). A coalescing air filter is recommended for all applications due to the close
tolerances in the positioner.
Apex A9000 positioner accessories: Optional analog feedback system as well as lim it switch unit and a directly
attachable double acting module.
NOTE: The air supply must conform to ISA 7.0.01 or IEC 770 (a dew point at least 10°C/18°F below ambient temperature,
particle size below five microns
– one micron recommended – and oil content not to exceed one part per million).
