We see from your search that you're looking for information on the term "Pneumatic Actuators",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Automatic transmission tackles heavy duties from
Zeroshift, which we summarised at the time by saying "Transmission system will improve fuel economy and refinement, reduce emissions and provide smooth gear changing with zero torque interruption".
Earlier in the week,
we featured the news release Valve actuators control Irish gas supply from
Rotork Skilmatic: "Each metering line has been equipped with two failsafe, spring-return modulating Skilmatic SI - ZL actuators, retrofitted on existing CCI globe control valves".
In November 2007, we covered the news from Festo
concerning its CPV10 Ex-i
- take a look at Valve terminal suits explosive applictions
which says: "The connector enables all pneumatic connections to be made via a single multiway plate, which incorporates its own sealing ring and only requires one rectangular cut-out in the cabinet".
Take a look also at the news release from Rotork Controls, Valve actuators chosen for water treatment,
as well as Ball valves handle low and high pressures from Swagelok,
and Actuators chosen for gas projects from Rotork Controls.
