Several types of valves are well - suited
for 180 - degree pneumatic actuators due to their characteristics and the
nature of the actuator's operation. Here are the main ones:
Ball valves: They are a common choice. Ball
valves have a simple structure with a spherical disc that rotates 180 degrees
to control the flow. They offer low - resistance flow, excellent sealing
performance, and can handle a wide range of fluids, including gases, liquids,
and slurries. This makes them suitable for various applications such as in the oil
and gas, water treatment, and chemical industries.
Butterfly valves: These valves are also
frequently used with 180 - degree pneumatic actuators. Butterfly valves have a
disc that rotates around a central axis, similar to the action of a 180 -
degree pneumatic actuator. They are lightweight, compact, and have a quick -
opening and closing action. They are suitable for applications where space is
limited and a relatively large flow area is required, such as in HVAC systems
and some industrial fluid - handling processes.
Plug valves: Plug valves have a cylindrical
or conical plug that rotates to control the flow. They are known for their
tight shut - off capabilities and can handle high - pressure and high -
temperature applications. The 180 - degree rotation of the pneumatic actuator
is well - matched to the operation of plug valves, making them a good choice
for certain industrial processes where reliable isolation and control of flow
are essential.
