The
positioner serves to position pneumatically actuated
diaphragm valves. The positioner is an electro-
pneumatic position controller for the pneumatically
actuated continuous diaphragm valve. The device
includes the following main function groups: a
feedback/positional transducer, an electropnuematic
system and a microprocessor electronic system.
The feedback/positional transducer measures the
actual position of the continuous valve. The microprocessor
electronic system continuously compares the actual
position (actual valve) with a desired position
value that was preset via the standard signal
input and supplies the result to the position
controller. If an error exists, the electropneumatic
system causes the actual position to be appropriately
corrected. |
As
with other Aquasyn components, our pneumatic actuators
provide design and construction which meet or
exceed industry standards. The actuators feature
lightweight performance plastic housings, precision
stainless internals, and O-rings machined and
molded to tight tolerances. Only high quality
materials are used for long, trouble free performance.
Like
our manual bonnets, all actuated bonnets feature
our patented Tork-Tite® feet and cover a
complete range of automation requirements from
basic on/off service to fine modulating control.
