Product Description
3.1
General Product Description
The Argus Ball Valve has many innovative design features that represent the highest
standards in valve technology.
The Argus Ball Valve EK, FK and HK series are used as bubble-tight shut-off devices or shut-off
valves in piping systems and containers used for processing, handling and transporting liquid
or gaseous substances and solid materials.
Argus Ball Valves are composed of a body with a recess for a cylindrical perforated ball for
rough flow control. The ball is either trunnion-mounted or floating. Depending on their size,
Argus Ball Valves can be opened and closed manually using a valve wrench, handwheel
with manual gearbox or opened and closed automatically using a hydraulic, pneumatic or
electric actuator.
The Argus Ball Valve is open when the hole of the Argus Ball Valve is in line with the flow and
closed when it is turned by 90 degrees. The wrench lies flat in alignment with the flow when
open, and is perpendicular to it when closed, allowing easy visual confirmation of the
valve's status.
Argus Ball Valves are durable, perform reliably after many cycles, and close securely even
after long periods of non-use. These qualities make them an excellent choice for shutting off
and controlling applications, where they are often preferred over gates and globe valves.
Argus Ball Valves are used in the chemical, process, petrochemical, refining and gas
industries.
